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
