Subject: General Aptitude · Chapter: Ratio and Proportion · Exam: · Marks: · Difficulty:
Divide ₹6450 among A, B, C and D such that when A gets ₹9, B gets ₹8; when B gets ₹6, C gets ₹5 and when C gets ₹4, D gets ₹3.
Answer
Explanation
$A:B = 9:8$, $B:C = 6:5$, $C:D = 4:3$. Combining these to a common scale: $A:B:C:D = 27:24:20:15$. Sum of ratio terms = (27+24+20+15) = 86. A's share = $₹\left(6450 \times \frac{27}{86}\right) = ₹2025$; B's share = $₹\left(6450 \times \frac{24}{86}\right) = ₹1800$; C's share = $₹\left(6450 \times \frac{20}{86}\right) = ₹1500$; D's share = $₹\left(6450 \times \frac{15}{86}\right) = ₹1125$.
