Correct Answer: C [Third offer]
Explanation:
(i) Equivalent discount
\(=\Big(25+15)-\frac{25 \times 15}{100}\Big)\%\)\(=40-3.75\)
=36.25
(ii) Equivalent discount
\(=\Big(30+10)-\frac{30 \times 10}{100}\Big)\%\)
\(=40-3\)
=37
(iii) Equivalent discount
\(=\Big(35+5)-\frac{35 \times 5}{100}\Big)\%\)
\(=40-1.75\)
\(=38.25\)
Now we can easily say that third discount is best.
Hence option c is our answer.
