SSC CGL - 03 Dec 2022 - Shift 2 • Quantitative Aptitude • Q53

If ∆ ABC ~ ∆ FDE such that AB = 9 cm, AC = 11 cm, DF = 16 cm and DE = 12 cm, then the length of BC is:

Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. 6346{{3} \over 4}.

∆ ABC ~ ∆ FDE and AB = 9 cm, AC = 11 cm, DF = 16 cm and DE = 12 cm

According to the property of a similar triangle, if two triangles are similar then the ratio of their corresponding sides is also equal.

⇒ AB/DF = BC/DE

⇒ 9/16 = BC/12

⇒ 27/4 = BC

⇒ BC = 6346{{3} \over 4}
