If ARTS = 1870; MART = 5187; CHART = 43187; then MARCH = ?

The correct answer is Option (3) → 51843

Each letter stands for one fixed digit, in the same position as the letter. Line up each word with its code to read off the digits.

• ARTS = 1870: A = 1, R = 8, T = 7, S = 0

• MART = 5187: M = 5 (A, R, T as before)

• CHART = 43187: C = 4, H = 3

• MARCH: M A R C H = 5 1 8 4 3, that is, 51843
