If P is 25% more than Q and R is 40% less than the sum of P and Q, then by what percentage is R more than P?
6%
12%
8%
14%
Answer: C
Solution: Let Q = 100. Then P = 125. The sum P + Q = 225. Since R is 40% less than this sum, \(R=225\times0.60=135\). R is 10 more than P. Percentage increase \(=\frac{135-125}{125}\times100=8\%\). Trick: Assume Q = 100, calculate P and R, then compare R with P.
यदि P, Q से 25% अधिक है और R, P तथा Q के योग से 40% कम है, तो R, P से कितने प्रतिशत अधिक है?
6%
12%
8%
14%
उत्तर: C
हल: Q = 100 मानें। तब P = 125 होगा। P + Q = 225। R इस योग से 40% कम है, इसलिए \(R=225\times0.60=135\)। R, P से 10 अधिक है। प्रतिशत वृद्धि \(=\frac{135-125}{125}\times100=8\%\)। ट्रिक: Q = 100 मानकर P और R निकालें, फिर R की तुलना P से करें।
