Q) In the given figure, XY || QR, (PQ) / (XQ) = 7 / 3 and PR = 6.3 cm. Find the length of YR.

(Q 21 B – 30/2/2 – CBSE 2026 Question Paper)
Ans:
Step 1: Since, by BPT theorm, we know that,
if XY || QR, then ![]()
Step 2: After substituting given values, we get:
∵ PQ = 7 cm, XQ = 3 cm, PR = 6.3 cm
∴ ![]()
∴ YR =
= 0.9 x 3 = 2.7 cm
Therefore, the length of YR is 2.7 cm.
