10
12
11
8
9
Option B
x+(x+2)+(x+4)=42 (given the intervals are 2 years)
3x+6=42 
x =36/2=12
 Age of the youngest brother=12 years

20
30
40
50
25

7. A florist choose one rose at random from the basket which have rainbow colors of roses. what is the probability of choosing yellow color rose?
1/5
1/8
1/9
1/7
1/4
Option D
S=(rainbow color roses)
S=(V,I,B,G,Y,O,R)=N(S)=7
P(Yellow rose)=P(S)/N(S)=1/7 (Only one yellow rose)

8. How many multiples of 2 are there in 10 to 80?
34
35
36
33
40
Option C
Multiples of 2 =>last digits must be 0, 2, 4, 6, 8
And first digit 1,2 ,3,4,5,6,7,
So there are 7 choices for the first number and 5 choices for the second number.
So there are 5x 7 =3 5 + 1= 36 (include 80) multiples of 2 in between 10 and 80.

9. In a shop two partners invested in the ratio 10:20 and they got the profits in the ratio 5:4.If the first partner invest the money for 10 months the how many months the second partner invested?

Investment ratio: 10:20
Profit ratio :5:4
First partner invested 10 months.
Second parner invested x (take) months.
So 10 x 20 / 10 x x = 5/4
20/x = 5/4
x = 16 months
