Question

a man sold two houses for 195500 each he gain 15% on one house and lost 15% on other find his total gain or loss percent

Answer 1

first house=
profit % = 15%
profit ₹= 15 % of 100 = ₹ 15
let the cost price be ₹ 100
s.p. = cp+profit
sp = 100+15
sp = ₹ 115
if sp is ₹ 115, cp is ₹ 100
= if sp is ₹ 195500
therefore cp = 100 ÷ 115 × 195500
₹ 170000
profit % = cp/100 × profit
170000/100× 15= ₹ 25500
second house =
loss % = 15%
loss= 15% of 100= ₹15
let the cp be ₹ 100
sp = cp + profits
sp = 100 + 15=115
if sp is ₹ 115,cp is ₹ 100
if sp is ₹ 195500
therefore cp = cp / 100 × profit
170000/100× 15= ₹ 25500
