Hi..

Say total is x

Operating expenses are 63%of x or 0.63*x..

So we require to know x

Let's see what the statements tell us

1) total budget is $9 million.

The value of x is given directly..

So Ans is 0.63*9=$5.67 million

Sufficient

2) school spent $2.1 million on school aid..

So 24%of x =2.16...

Again x can be found ..

0.24x=2.16........x=216/24=9

So X is $9 million..

So 0.63x=0.63*9=$5.67 million

Sufficient

D
