Question

If a groundnut weighs 9 g and a mango weighs 72 g, then 4 mangoes and ___ groundnuts weigh the same.

• A. 28
• B. 30
• C. 32
• D. 34

Answer 1

The correct option is C 32

A mango weighs 72 g.
Thus, 4 mangoes weigh 72 g × 4 = 288 g.

A groundnut weighs 9 g.
Therefore, the number of groundnuts in 288 g is $\frac{288\text{g}}{9\text{g}}=32.$
