Solutions:

Ans(1-5)

Ans.1(1) Required % = 810/840 × 100 = 96.43%

Ans.2(3) Required No of girls in cricket and Hockey
= 480 + 840 = 1320

Ans.3(5) Required % =1395/7500×100 = 18.6%

Ans.4(2) Total No. of Boys in Tennis and volleyball
= 720+900 = 1620

Ans.5(4) 675

Ans.6(3) Let the present age of Suraj = x year
so, Present age of Ritik = (20-x)year
According to question
x+4 = 2(20-x)
x+4 = 40-2x
x = 36/3 = 12 year
Present age of Ritik = 20-12 = 8 year

Ans.7(3) Manoj’s present age = 12+6 =18 years
Present age of Vini’s father = 2(18+8) = 52 years
Vini’s present age = 52×1/8 = 6 4/8years = 6years 6 months

Ans.8(5) Let Rahul’s present age = x years
So, age of Deepak = (x+3x) = 4x year
(4x+10) = 3/2 (x+10)
x = 2

Ans.9(5) F+S/2 = 23
F+S = 46 —- (I)
F – S = 20 —- (II)
then, F = 33 S = 13
Required Ratio =13+2/33+2 = 15/35 = 3 /7

Ans.10(3) Let the present age of Rani = x
Present age of Deepa = 2x
According to the question
= X-16 / 2X-16 = 3/10
x = 28
So, present age of Rupa = 28 × 2 = 56 years
