Question

30 %of the sum of two no. Is equal to 40%of their differences. then find ratio of big no. to small no.

Answer 1

The ratio of bigger number to smaller number is 1:-1.

• Let the two numbers be a and b.
• According to the given condition, 30% of the sum of two numbers is equal to 40% of the difference between them.

0.3(a+b) = 0.4(a-b)

0.1a + 0.1b = 0

a:b = 1: -1

• As the above ratio is greater , it is ratio of bigger number to smaller number.
