Correct Answer: 24 : 63 : 175


Solution : Given: p : q = 4 : 7 and q : r = 3 : 5
Equating q in both the ratio, we get p : q : r = 12 : 21 : 35
Let the p, q, and r values be 12k, 21k, and 35k.
So, 2p : 3q : 5r = (2 × 12k) : (3 × 21k) : (5 × 35k) = 24k : 63k : 175k = 24 : 63 : 175
Hence, the correct answer is 24 : 63 : 175.
