Question

A man sold two articles for rs.12 each, on the first he gains 20% and on the second he losses 20%. Find the amount of profit or loss on the whole transaction

Answer 1

Answer:240

Step-by-step explanation:

one man sold two articles for rs.12 multiply 20×12=240 and you get the answer 240

Answer 2

Answer:

Case 1:

Given-

S. P=12 rupees

Gain=20%

Solution-

Let the C. P of 1st article be 'x'

Therefore,

X + 20% of X = 12

X+ 0.2 X = 12

1.2 X = 12

X = 10 rupees

Case 2:

Given-

S.P=12 rupees

Loss = 20%

Solution-

Let the C. P of 2nd article be 'y'

Therefore,

Y - 20% of Y = 12

Y - 0.2 Y = 12

0.8 Y = 12

Y = 15 rupees.

Now, Total C. P = 10+15 =25

Total S. P = 12+12 =24

Total transaction= Total CP - Total SP = 25-24= - 1(loss)
