A. 18
B. 12
C. 32
D. 42
E. 65

Answer 1

Answer 12

12.5×(14÷8.75)+42= (12.5×1.5)+42=

20+45=62

So 62= 50+?

? =12

Answer 2

Solution:

Before simplify this expression we must know the BODMAS rule

$12.5 \times 14 \div 8.75 + 42 = 50 +? \\ \\ 12.5 \times \frac{14}{8.75} + 42 = 50 +? \\ \\ 12.5 \times 1.6 + 42 = 50 +? \\ \\ 20 + 42 = 50 +? \\ \\62 = 50 +? \\ \\ so \\ \\? = 12 \\ \\62=50+12\\\\62=62$
Hence option B is correct.

Hope it helps you.
