Answer 2

Answer:

the LCM & HCF of two numbers m & n are equal then m and n are

The HCF and LCM of two numbers m and n are respectively 6 and 210. If m + n = 72, then 1/m + 1/n is equal to

1/35

3/35

5/37

2/35

Correct Option: D

We have, m x n = 6 x 210 = 1260

∴ 1/m + 1/n = (m + n)/mn = 72/1260 = 4/70 = 2/35
