Question

If the two number are in the ratio of 2:3 and product of their LCM and HCF is 38400.what will be the sum of the numbers?

Answer 1

Explanation:

a * b = LCM * HCF

2x*3x = 38400

6x² = 38400

x² = 6400

x = 80

ratio of these two numbers = 2x : 3x

numbers = 160 , 240

Sum of these two numbers

= 160 + 240 = 400
