CBSE Class 10 Maths Basic Proportionality Theorem

Q.

In ABC, DE is parallel to BC. If AE = x cm, EC = (x 2) cm, AD = (x + 2) cm and DB = (x 1) cm, then find the value of x.



Q.

In triangle KMN, PQ intersects KM and KN at P and Q, respectively, such that KP = 1.4 cm, KM = 5.6 cm, KN = 7.2 cm and PQ is parallel to MN. Find KQ.



Q.

In ABC, DE||BC and AD/DB = 3/5. If AC = 5.6 cm, find AE.



Q.

In DKMN, PQ||MN. If KP / PM = 4 /13 and KN = 20.4 cm. Find KQ.
