Answer & Explanation

1.(3)      2.(2)       3.(2)     4. (5)     5.(3) Ratio =24/16= 3 : 2

Solutions (6-10)

6. 3;      Both statements are required for answer.

SP = 12000, Profit = 20%

Cost Price = 1000 ie profit = 2000

Total profit = 2000 × 20 = 40000

7. 3;     From statement I:

x = 4y                             …(i)

From statement II:

x – 5 = 7(y – 5)

7y – x = 30                    …(ii)

Solving equations (i) and (ii), x = 40, y = 10

8. 5;      Data is not sufficient to find the answer.

9. 4;      Both statements alone are sufficient to answer.

Let be speed = v, distance = x, time = t

t =  x/v           …(i)

From statement I:

x/5v/4=t – 20

4x/5v= t – 20

x/v = 5/4(t – 20)           …(ii)

From (i) and (ii), t =  5 / 4(t – 20)

4t = 5t – 100

t = 100 seconds

From statement II:

x / v / 2 = t + 100

2x / v = t + 100

t + 100 = 2t

t = 100 seconds

10. 3;    Both statements are required to answer the question.

From statement I:

1/v =  10 seconds                   (1 = length, v = speed)

From statement II:

v = 10 m/sec

1 = 10 × v = 100 m
