Logarithm Actual Question in CMAT 2023 Slot - 2

12 December 2023 · by CMATking

Q1. If 5^a = 9^b = 2025, then the value of ab / a+b.

A 4
B 3
C 2

D 1

EXPLANATION

C

5^a = 2025

Applying log on both the sides, we get

Similarly, we get b = log₉ 2045

1 / a = log₂₀₄₅ 5

1 / b = log₂₀₄₅ 9

1 / a + 1 / b = log₂₀₄₅ 45

ab / a + b = log₄₅ 2045 = 2
