1.	47% of 600 + ?% of 300 = 3991). 452). 413). 424). 39
Answer» The given expression: 47% of 600 + ?% of 300 = 399 $(\Rightarrow \frac{{47}}{{100}} \times 600 + \frac{?}{{100}} \times 300 = 399)$ ⇒ (47 × 6) + (? × 3) = 399 ⇒ 282 + (? × 3) = 399 ⇒ (? × 3) = 399 – 282 ⇒ ? = 117 ÷ 3 = 39

Answer»

The given expression:

47% of 600 + ?% of 300 = 399

$(\Rightarrow \frac{{47}}{{100}} \times 600 + \frac{?}{{100}} \times 300 = 399)$

⇒ (47 × 6) + (? × 3) = 399

⇒ 282 + (? × 3) = 399

⇒ (? × 3) = 399 – 282

⇒ ? = 117 ÷ 3 = 39
