The product of HCF and LCM of two numbers is 2535. The smaller number is 60% of the larger number. Find the difference of between the numbers.1). 282). 273). 244). 26

Answer»

Let the first NUMBER be 5a.

So, the second number = 60% of 5a = 3/5 × 5a = 3a

HCF × LCM = 1st no. × 2nd no.

2535 = 5a × 3a

⇒ 2535 = 15a2

⇒ a2 = 169

⇒ a = 13

DIFFERENCE between the numbers = 5a - 3a = 2a = 2 × 13 = 26
