Rayan invested certain amount for two rates of simple interests at 6% p.a. and 7% p.a. What is the ratio of Rayan’s investments if the interests from those investments are equal?

A. 4 : 3
B. 3 : 2
C. 6 : 5
D. 7 : 6
E. None of these
Explanation:
Let x be the investment of Rayan in 6% and y be in 7%
x(6)(n)/100 = y(7)(n)/100
=> x/y = 7/6
x : y = 7 : 6
