Answer & Explanation
  1. (c); Let the speed of a boat & stream be x & y kmph.

According to question

25/(x-y)+39/(x+y)=8 …………(i)

&

35/(x-y)+52/(x+y)=11………..(ii)

From (i) and (ii)

x=9, y=4

Hence speed of stream, y=4

 

  1. (d); Let the number of green marble=x

So, xC1/24C1=2/3

x=16

So, No. of blue marble=24-16=8

  1. (b); Total number of cases=10C4

Favourable number of cases=(4C2X6C2)/10C4=9/21

4(c); Probability of selecting black ball from 1st boy.=(1/2)X(6C1/14C1)=3/4

Probability of selecting black ball from 2nd boy=(1/2)X(7C1/11C1)=7/22

Required Probability=(3/14)+(7/22)=41/77

  1. (b); Let diagonals of rhombus be x & y.

Given x+y=10

½ x.y=9

xy=18

x^2+y^2=(x+y)^2-2xy

=(10)^2-2.18

=(10)^2-2.18

=64

  1. (a); Side of square=(784)^(1/2)=28

2pi R=(11/4)X4X28

R=28

Diameter of another circle B=1/2 R=(1/2)X28=14

r=14/2=7

Area of circle=B=pi*7^2=154 cm^2

  1. (c); Number of tiles needed=(Area of square room)/(Area of tile)

=(10X100X10X100)/(50X50)

=400

  1. (d); Ratio of the amount collected from 1st& 2nd class fairs=(3X1): (1X50)= 3 : 50

Required Amount=2650X(50/53)=2500

  1. (a); 80% of total marks=80% of 105X5=420

So, obtained marks in Science=420-(89+92+98+81)=60

  1. (e); Let the rate of Interest allowed by bank be r%

(12000X5X10)/100)-((12000X3Xr)/100)=3320

r=7(4/9)%

  1. (a); Required Average=(5000+10000+15000+30000+40000+50000)X1/6

=25000

  1. (c); Required Percentage=(40000/250000)X100=160%
  2. (a); Required Number=90000X(70/100)=63000

14 (a); Required Ratio=10000 : 75000= 2 : 15

15 (e); Required Percentage=(45000-30000)X100)/45000

=33% Approx
