P is 20% more than Q and 40% less than R. If value of Q is Rs. 150, then what is the value of R (in Rs.) ?

Answer : Option C

Explanation :

$mathrm{Q}=mathrm{Rs} .150$ $herefore mathrm{P}=mathrm{Rs} .left(frac{120 imes 150}{100} ight)=mathrm{Rs} .180$ $herefore mathrm{R}=frac{180 imes 100}{60}=mathrm{Rs} .300$ Alternative : According to the question, $frac{mathrm{P}}{mathrm{Q}}=frac{120}{100}=frac{6 imes 3}{5 imes 3}=frac{18}{15}$ $frac{mathrm{P}}{mathrm{R}}=frac{60}{100}=frac{3 imes 6}{5 imes 6}=frac{18}{30}$ ( (i) × 3 and (ii) × 6)
