Question

Amit sold an umbrella for Rs.680, losing
15%. The cost price of the umbrella is:
a) Rs.782
b) Rs.800
c) Rs.578
d) None of these​

Answer 1

Answer:

Let us consider that, the cost price of the umbrella be Rs. x

Given,

rate of loss = 15%

selling price = Rs. 680

Then loss = Rs. x * 15/100 = Rs. 3x/20

By the given condition,

selling price = cost price - loss

i.e., 680 = x - 3x/20

or, (20 - 3)/20 * x = 680

or, 17x/20 = 680

or, x = 680 * 20/17

or, x = 800

Hence the cost price of the umbrella is Rs. 800

Step-by-step explanation:

Answer 2

Answer:

SP = 680

loss % = 15 %

let CP be x so,

According to question,

x - 15% of x = 680

x - (15/100) × x = 680

x - (3x/20) = 680

17x/20 = 680

x = (680×20)/17

x = 800

So, CP is Rs 800

option (b) is correct
