ML Aggarwal CBSE Solutions Class 8 Math 6th Chapter Percentage and its Applications Exercise 6.3

(1) (i) MP = 575 /-

Dis = 12%

SP = 575 X 88/100

= 506/- (Ans)

Dis = 575 – 506 = 69/- (Ans)

(ii) MP = 12750/-

dis = 8 1/3 % = 25/3 %

SP = 12750 X (100 – 25/3)/100

= 12750 X (275/3)/100

= 1275 X 275/10 X 3

= 11687.5/-

Dis = 12750 – 11687.5

= 1062.5/-

(2) (i) MP = 780/-

SP = 721.50/-

Discount = 780 – 721.50

= 58.50/- (Ans)

Dis % = 58.50/780 X100 =

= 5850 X 100/100 X 780

= 7.5% (Ans)

(ii) AP = 28500/-

SP = 24510/-

∴ dis = 28500 – 24510

= 3990/- (Ans)

Dis % = 3990/28500 X100

= 14% (Ans)

(9) CP = 1600/-

(i) Let, MP = x

Given, CP price is 20% below the market price.

∴ According to qne –

(100-20)x/100 = 1600

Or, 80x/100 = 1600

Or, x = 1600X10/8 = 2000

∴ MP = 2000/- (Ans)

(ii) dis = 16%

∴ SP = 2000X84/100

= 1680/- (Ans)

(iii) Profit = 1680 – 1600

= 80/-

Profit % = 80/1600 X 100

= 5% (Ans)
