There are tree numbers P, Q and R. 30 percent of P is equal to the 15 percent of Q. 20 percent of Qis equal to the 10 percent of R. By what percent is R more than P?
Answer & explanation
Correct answer: option 2
According to question ,
30% of P = 15% of Q
so ratio of P & Q = 1 : 2
& 20% of Q = 10% of R
so, ratio of Q & R = 1 : 2
Now P : Q : R = 1 : 2 : 4
Difference of P & R = 4R - 1R = 3R
Required percentage = \(\frac{3R}{1R}\)× 100% = 300%
