Question

If two different amounts in the ratio 8:9 are invested in Companies P and Q respectively in 2002, then the amounts received after one year as interests from Companies P and Q are respectively in the ratio?

• A. 2:3
• B. 3:4
• C. 6:7
• D. 4:3

Answer 1

The correct option is D 4:3

Let the amounts invested in 2002 in Companies P and Q be Rs. 8x and Rs. 9x respectively.
Then, interest received after one year from Company P = Rs. (6% of 8x)
$=Rs.\frac{48}{100}x$
and interest received after one year from Company Q = Rs. (4% of 9x)
$=Rs.\frac{36}{100}x$
$\therefore$ Required ratio = $\frac{\left(\frac{48}{100}x\right)}{\left(\frac{36}{100}x\right)}=\frac{4}{3}$
