Step-by-step explanation:

and

the amount invest on 15percent= y

x+y =12000 _ _ _ _ (1)

Given,

To invest some amount 10percent and the rest at 15 percent,

we should be invest to each rate to yield 12 percent on the total amount invested

10x/100 + (15y/100) =(12/100) ×12000

2x +3yb =28800_ _(2)

SOLVING (1) & (2) we get

The amount to be at 10 percent =Rs7200

The amount to be invest 12percent = Rs 4800
