Question

ravi had some marbles he gave 1upon 7 of the marbles to his brother and 1 upon3 of the remaining to his friend if ravi has24 marbles leftwith him , how many marbles did he gave in the beginning

Answer 1

Answer:

let, Ravi had = x

he gave his brother= x/7

now he had = x-(x/7)=6x/7

he gave his friend=( 6x/7)*1/3= 2x/7

now he had =( 6x/7) -(2x/7)= 4x/7

4x/7 =24

or, x = 42

so he gave 42/7= 6 marbles to his brother
