Question

In a school the ratio of the no. Of large classes is3:4 . If the no. Of small classes is 20 then find the no. Of large rooms ?

Answer 1

Hey sup!

Ratio of large classes to small classes=3:4

So let the large classes and small classes be 3k and 4k respectively.

Also small classes=20.
=>4k=20.
=>k=20/4=5.

So number of larger classes=3k= 3*5 = 15.

Hope it helps.
