Annual Rate of Interest Offered by Two Finance Companies Over the Years.
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?
2:3
3:4
6:7
4:3
Correct answer is D
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. (48/100) x.
and interest received after one year from Company Q = Rs. (4% of 9x)
= Rs. (36/100) x.
Therefore Required ratio = ( (48/100) x )/( (36/100) x ) = 4/3
