Question

The average weight of males is one-third of the total number of female in the college and ratio of number of male and female in the colleges is 3: 6. If the total number of male and female in the college is 630, then what is the total weight of the male in the college ?

Answer 1

Answer:

total no. of male +female = 630(given)

asli ratio (male:female)=3:6=1:2

let ratio be 1x :2x=3x

I.e. 3x=630

x=630÷3=210

now male = 1x =1×210=210

female=2x=2×210=420

given average weight of male is 1/3 of no. of female

i.e. 1/3(average weight of male)=total no of female

I.e. average weight of male=420×3=1260 kg
