If (pa + qb): (pc + qd) :: (pa – qb): (pc – qd) prove that a: b :: c: d.

Class 10 | Exercise 1 | ICSE | Maths | ML Aggarwal | Ratio and Proportion

If (pa + qb): (pc + qd) :: (pa – qb): (pc – qd) prove that a: b :: c: d.

It is given that

(pa + qb): (pc + qd) :: (pa – qb): (pc – qd)

We can write it as

Therefore, it is proved that a: b :: c: d.
