Explanation : Let, the man's income be Rs.x.

Expenditure on food = x/3 and expenditure on house rent = 2x/5

His saving = x - (x/3 + 2x/5) = 4x/15

So,4x/15 = 2000

or x =( 2000 X 15 ) /4 = 7500.

The ratio between the present ages of A and B is 2 : 3 respectively. Four years ago, the ratio between their ages was 5 : 8. respectively. What will be A�s age after 7 years ?

1)	29 yrs	2)	35 yrs
3)	31 yrs	4)	33 yrs
5)	None of these

Answer : 31 yrs

Let, the present ages of A and B be 2x years and 3x years respectively.

So, (2x-4)/(3x-4) = 5/8

or 16x - 32 = 15x -20

or x = 12

Therefore, the Ages of A after 7 years = 2x + 7 = 2 x 12 + 7 = 31 years

Three men or eight boys can do a piece of work in 17 days. How many days will two men and six boys together take to finish the same work ?

1)	9 days	2)	11 days
3)	14 days	4)	12 days
5)	None of these

Answer : 12 days
Explanation :

3 men = 8 boys

2 m = (8/3)x2 = 16/3 boys.

(2 men + 6 boys) = (16/2)+6 boys = 34/3boys

8 boys can complete the work in 17 days

or 34/3boys boys can complete the work in x days

or (34/3) : 8 = 17 : x

or x =(17x8x3)/34 = 12 days

Three- tenth of a number is equal to 36% of another number. If the sum of these two numbers is 88, then what is the value of the smaller number ?

1)	38	2)	40
3)	48	4)	56
5)	None of these

Answer : 40
Explanation :

Let, one number be x.

The other number = (88 - x)

x x 3/10 = (88 - x) x 36/100

= 30x = 3168 - 36x

x = 3168/66 = 48

The smaller number = 88 - 48 = 40

x = 260/26 = 10

C.P. of 1 tube light and 6 bulbs

= 5 x X + 6 x 2 xX

= 5 x 10 + 12 x 10 = Rs.170
