Question

166 cakes were distributed among a group of 67 children. Each senior got 3
cakes while each junior 2. Find the number of juniors in the group.




​

Answer 1

Answer:

35

Step-by-step explanation:

let the number of seniors in the group be x and the number of juniors in the group be y.

then,

x+y=67-(i)

3x+2y=166-(ii)

multiplying eqn. (i) with 2, we get-

2x+2y=134'(iii)

substracting eqn. (iii) from (ii), we get-

x=32

by putting this value in equation (i),

y=35
