1.  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: Option D

Explanation:

Let the amounts invested in 2002 in Companies P and Q be ₹ 8x and ₹ 9x respectively.

Then, interest received after one year from Company P = ₹ (6% of 8x)
= ₹ 48 x.
100
and interest received after one year from Company Q = ₹(4% of 9x)
= ₹ 36 x.
100

Therefore Required ratio =
( 48 x )
100
= 4 .
( 36 x )
100
