a. How many candidates have passed?
b. if 96% of the candidates has passed, how many more would have passed?​

Answer 1

Answer:

a) 598

b) 26

Step-by-step explanation:

In an examination, out of 650 candidates 92% has passed.

The number of candidates passed = 92% of 650

   $\sf =\dfrac{92}{100} \times 650 \\\\ \sf =\dfrac{92}{10} \times 65 \\\\ \sf =\dfrac{92}{2} \times 13 \\\\ \sf =46 \times 13 \\\\ \sf = 598$

So, 598 candidates have passed.

If 96% of the candidates has passed, the number of candidates passed

$\sf =\dfrac{96}{100} \times 650 \\\\ \sf =\dfrac{96}{10} \times 65 \\\\ \sf =\dfrac{96}{2} \times 13 \\\\ \sf =48 \times 13 \\\\ \sf = 624$

Increase in the number of passed candidates = 624 - 598

= 26

Therefore, 26 more candidates would have passed.
