The reciprocal of the hcf and lcm of two are 1/15 and 1/312 .if one of the number is 24 then other no. is Options.
A) 126  B) 136  C) 146  D) 156  E) 195

Rationale: "reciprocal of the hcf and lcm of two are 1 / 15 and 1 / 312 so , hcf = 15 , lcm = 312 lcm * hcf = product of two numbers = a * b = > b = lcm * hcf / a so , other = 15 * 312 / 24 = 195 answer : e"
Answer: E
