Answer & Explanation

1.(b)
Other number= (693×11)/99
=77
2.(a)
Convert first all terms into cm.
i.e. 1575 cm, 1125cm, 765cm.
Now whenever we need to calculate this type of question, we need to find the HCF. HCF of above terms is 45.
3.(b)
In this type of question, its obvious we need to calculate the HCF, trick is
HCF of (1661 – 10) and (2045 -13)
= HCF (1651, 2032) = 127
4.(c)
HCF of (237-132), (132-62), (237-62)
= HCF of (70,105,175) = 35
5.(c)
LCM of 27-18-12-15 is 540.
After dividing 9999 by 540 we get 279 remainder.
So answer will be 9999-279 = 9720
6.(c)
L.C.M. of 60 and 62 seconds is 1860 seconds
1860/60 = 31 minutes
They will beep together at 10:31 a.m.
7.(b)
HCF of (400-9, 435-10, 541-14)
HCF of (391, 425, 527) = 17
8.(a)
HCF * LCM = 84942, because we know
Product of two numbers = Product of HCF and LCM
LCM = 84942/33 = 2574
9.(a)
Let the numbers be 3x and 4x. Then, their H.C.F. = x. So, x = 4.
So, the numbers 12 and 16.
L.C.M. of 12 and 16 = 48.
10.(b)
LCM of fraction=LCM of numerator /HCF of denominator
LCM of numerato=8 , HCF of denominator=3
=8/3

Answer & Explanation

It is evident that one word and one number are arranged in each step. The numbers are arranged from the left and the words are arranged from the right. In the first step the word which comes last in the dictionary is shifted to the extreme right, while the highest number is shifted to the extreme left. In the second step the word which appears at the second last position in dictionary order is moved to the extreme right while the lowest number is shifted to the extreme left position. The same procedure is followed to get the final output.

Directions: (6 – 10): Read the following passage carefully and answers the questions given below it. Certain words are given in bold to help you locate them while answering some of the questions.
Seventeen years after the first successful transplantation of cells harvested from the umbilical cord, the use of cord blood as a viable alternative to bone marrow as a sources of stem cells is gaining importance. The cord blood that remains in the placenta after birth is routinely discarded as waste despite the fact that it has sufficient quantity of stem cells capable of curing diseases. Although precise data are not available, it is thought that 5,000 to 6,000 cord blood transplantations have been performed worldwide. With the number of births in India running into several millions a year, the potential to fight disease and save lives is immense even if the cord blood from a small fraction of newborns can be collected and preserved. There are compelling reasons for saving cord blood – the avoidance of the need for a perfect tissue match required in bone marrow transplants, the low rate of viral contamination and ready availability. The scope for using the cord blood later in the event of the child suffering from certain diseases is also a major attraction. 
It is this unique feature that has prompted some private companies in India, as in the developed countries, to get up facilities to collect and store cord blood, for a huge fee of course. Like their counterparts in the West, most of them resort to emotional marketing to sell the concept of cord blood serving as a biological insurance for use by the same child or another family member at a later date. How wise or relevant is it to save the newborn’s cord blood private banks?  The answer is not clear as no reliable estimates of the demand for stored cord blood are available. Empirical data on such contingencies are also scarce. According to the American Academy of Pediatrics, the chances of a child needing his or her own cord blood to treat a disease vary from 1 in 1000 to 1 in 200, 000. While medicine as it is currently practiced does not allow use of a child’s cord blood in the treatment of his or her genetic or leukemia, it does have it uses in treating other diseases. Private cord blood banking is much more relevant where a member of the family may have a current or potential need for stem cell transplantation. 
There is no disputing, the scientific fact the cord blood is a potential weapon to treat many diseases; and the number or diseases so treatable are likely, to increase in future. A good strategy   might be to have several publicity funded cord blood banks co-existing with private banks. Modeled along the lines to blood banks, the public cord blood banks can draw on altruism to get voluntary donations; and since cord blood is far more expensive to process than blood, it can be made available to suitable recipients on payment of a reasonable collection, processing and storage charge. At least one private cord blood bank relying on voluntary donations is in place. Priority must be given to the training of doctors and staff in the proper collection techniques. This is of paramount importance as the time of clamping the umbilical cord to collect cord blood is critical. Clamping the cord too early will increase the volume of cord blood collected but leave the new-born with a reduced blood volume and an increased risk of anemia in later life. To prevent exploitation of poor and vulnerable people, getting the written consent of parents for cord collection as well as the institution of in – house ethics committees must be made mandatory, and the legal requirement strictly enforced.

(5)  Cord blood is most important part of the blood

Q8. Which of the following has not been cited as a reason to promote the use of cord blood?
