Answer: 70
Explanation:Given ratio of girls : boys = 5 : 7 = 5/7
multiplying the antecedent and consequent by the same number, let by x,
girls = 5x, and boys = 7x
total = 120;
as par given 5x + 7x = 120
=> x = 120/12 = 10
hence, girls = 5 × 10 = 50
and Boys = 7 × 10 = 70 answer

- 31 kg
Answer: 31 kg
Explanation:Weight of A+B+C = 45 × 3 = 135 kg .....(i)
Wt. Of A+B = 40 × 2 = 80 kg .....(ii)
Weight of B + C = 43 × 2 = 86 kg ......
(iii)
Now on adding (ii) and (iii),
wt. of A+2B+C = 166kg
A+B+ C = 135 kg ....given (i)
On Subtracting (i)
B = 31 kg ..Ans

Answer: 13
Explanation:The sum of all numbers = 8 × 5 = 40
So, ? = 40 - (7+3+12+5) = 13 Ans.
