Question

if the selling price of t v set is equal to 6/5of its cp.find gain percent

Answer 1

you use gain formula

Answer 2

let,
the CP = 100 RS.
so, SP = 100×6/5
=> SP = 120rs.
gain = SP -CP
=> gain= 120-100
= 20 RS.
we know that,
gain percent = gain / CP × 100
=> gain percent = 20 / 100 × 100
=> gain percent = 20 % ( 100 to 100 cancelled)
