ICSE Prelims 2017 : Mathematics (The Heritage School, Kolkata)

x = 10pq/p+q

x/5p = (10pq/p+q)/5p = 2q/p+q

Applying C.D. method,

(x+5p)/(x-5p) = (2q + p + q)/(2q - p - q)

= (p+3p)/(q-p)

(x+5p)/(x-5p)+(x+5p)/(x-5p)

= (p+3p)/(q-p)+(p+3p)/(q-p)

= (2p+6q)/(q-p)

please check the answer is it correct or not
