Question

7. Shobhana bought a box for 1680 and had to
spend some amount to get it lacquered. If she got
a 15% profit by selling it for 2300, how much
did she spend on getting the box lacquered?​

Answer 1

Answer:

sp = cp + cp × x/100

so 2300 = y + y×15/100

2300 = y + 3y/20

2300 = 23y/20

100 ( × 10 × 2)

2000 = 2y

we see that 2000 is the initial amount we get when

she did not make any profit

so 2000 - 1680 = 320

she spent 320rs to get it lacquered

UR ANSWER IS 320
