Question

In an exam, Anwar and Fardoon scored$68\mathrm{and}70$marks respectively. In the next exam Anwar scored $12\%$ more than his earlier score while Fardoon scored $5\%$ more than his earlier score. How much did they score?

Answer 1

Step 1:Given

Anwar initial score is = $68$

He scored $12\%$ more in the next exam.

$$\begin{gathered} \frac{12}{100}\times 68 \\ \frac{816}{100} \\ 8.16 \end{gathered}$$

Anwar score in the next exam $=68+8.16=76.16$

Step 2: Fardonn score in the exam = $70$(given)

He scored $5\%$ more in the next exam.

$5\%\mathrm{of}70$

$$\begin{gathered} \frac{5}{100}\times 70 \\ \frac{350}{100} \\ 3.5 \end{gathered}$$

Fardoon score in the next exam

$$\begin{gathered} =70+3.5 \\ =73.5 \end{gathered}$$

Hence, they score $76.16\mathrm{and}73.5$ respectively in the next exam.
