hey guys...✌️✌️

need explanation with correct steps...

don't give unnecessary answers.....plss​

Answer 1

Answer:

Let the cost be Rs 100x

20% loss means selling price is Rs 80x

80x = 640

100x = 100/80 X 640 = Rs 800 = cost price

10% profit means selling price has to be Rs 880

Increase = 880-640 = Rs 240

Increase % 240/ 640 X 100 = 37.5%

hence 37%5 increase.

Answer 2

Given :-

• SP = Rs.640 when Loss is 20% .
• To make Profit of 10% , how much % SP inc. ?

Solution :-

in case 1 we Have :-

→ SP = Rs.640

→ Loss = 20%

→ CP = SP * 100 / (100 - Loss%)

→ CP = 640 * 100 / (100 - 20)

→ CP = 640 * 100 / 80

→ CP = Rs.800

Case 2 :-

→ CP = Rs.800

→ Profit = 10%

→ SP = CP * (100 + P%) / 100

→ SP = 800 * (100 + 10) / 100

→ SP = 800 * 110 / 100

→ SP = Rs.880

So, we Can Say That,

→ Increase SP = 880 - 640 = Rs.240 .

→ % increase = ( 240 * 100 ) / 640 = 37.5%

Hence, The Shopkeeper Has to increase His SP by 37.5% to Make a profit of 10%..
