Question

A and B each has some money. If A gives Rs 30 to B, then B will h e twice the
money left with A. But, if B gives Rs 10 to A, then A will have thrice s much as is
left with B. How much money does each have? use substitution method​

Answer 1

Let A has Rs.x and B has Rs.y

After giving Rs.30 to B ,

A has left with Rs. x-30 and B will have Rs.y+30

By the given condition

$\sf {y+30=2(x-30) (i)}$

After giving Rs.10 to A, B is left with Rs.y-10 and A will have x+10

$\sf {x+10=3(y-10) (ii)}$

Solving (i) and (ii) eq.

A has Rs.62 and B has Rs.34
