Q. 4 D4.5( 33 Votes )

The ratio of two

Answer :

Let a and b be two numbers.

Given that a:b = 31:23


Sum of a and b = a + b = 216


Let the first number ‘a’ = 31x


Then the second number ‘b’ = 23x


Consider a + b = 216


31x + 23x = 216


54x = 216


x = 216/54 = 4


The first number ‘a’ = 31x = 31 × 4 = 124


The second number ‘b’ = 23x = 23 × 4 = 92
