Question

In Fig. 4.246, if PB || CF and DP || EF, then AD/DE =​

Answer 1

Answer:

Given: PB||CF and DP||EF. AB = 2 cm and AC = 8 cm.

Given:

PB || CF, DP || EF.

AB = 2 cm, AC = 8 cm.

We need to find AD/DE.

By the basic proportionality theorem, we get,

Hence, we have

                       .......... (1)

Since DP || EF, we also get

AD/DE = AP/PF

AD/DE = 1/3                (using Equation(1))

Therefore, the correct answer is (b).
