Answer 2

Heya !!!

This is your answer.

Given :-

2:5 and 30:20.

Let us assume that they are equal.

So, 2:5::30:20.

In equal ratio, the product of outer ratio is equal to the product of inner ratio.
eg. in a:b::c:d.
a×d = b×c

So.....
2×20 = 40
5×30 = 150.

as they are not equal. so the ratio 2:5 and 30:20 are also unequal.

Hope it helps
