Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. 26.250.

L.C.M(35, and 42)

⇒ 35 = 5 × 7

⇒ 42 = 2 × 3 × 7

L.C.M = 2 × 3 × 5 × 7 = 210

H.C.F(32, and 40)

⇒ 32 = 2 × 2 × 2 × 2 × 2

⇒ 40 = 2 × 2 × 2 × 5

H.C.F = 2 × 2 × 2 = 8

Hence,

⇒ L.C.M/H.C.F = 210/8 = 26.250
