Answer 2

Answer:

12.5

approximately 13 boys

Step-by-step explanation:

this sum can be solve by equation method only,I think so,

let's take total number of boys as x,

money as y,

x + 10 = y - 5(x+10)

solving this will come as, 6x - y = 40 -----(1)

x - 15 = y + 15(x - 15)

solving this will come as, 14x + y = 210 -----(2)

solving 1 and 2, we get

x = 12.5 which will be 13 boys approx.

y = 35
