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

2. Cost of a table is Rs .5000 and selling price is Rs. 7000.What is the profit percent?
20
30
40
50
25

Profit % = p/c.p x 100
=2000/5000 x 100
P%=40

3. Ganesh can do a task in 4days . Prem can do a task in 6 days. How long if will take if both Ganesh & Prem work together?
1day 4hrs
2day 4hrs
2day 6hrs

Ganesh 1day work=1/4
Prem 1day work =1/6
(Ganesh+Prem) =1/4+1/6=5/12
So Ganesh& Prem will complete in 12/5=2day 4hrs together.

3
2
1
4
8

T=distance/speed
T=80/40=2hrs

5. what is the simple interest on Rs 60000 at 5 ½% per annum for 2 years?
5000
4500
6600
4000
6500

35
36
33
40

So 10 x 20 / 10 x x = 5/4
20/x = 5/4
x = 16 months
