Direction: What value should come in place of the question mark (?) in the following question? 12.5×14÷8.75+42=50+?

18
12
32
42

Correct Answer: 12

Explanation:

By replacing the “?” with “x”

(12.5×14÷8.75) x (100/100) + 42 = 50 + X

(125*140)/875 + 42 = 50 + X

140/7 + 42 = 50 + X

20 + 42 = 50 + X

62 = 50 + X

X = 62 - 50

X = 12
