A cloth merchant says that due to slump in the market, he sells the cloth at 10% loss but he uses a false metre scale and actually gains 15%. Find the actual length of the scale.
71.34 cm
Incorrect AnswerNone of these
Incorrect AnswerExplanation:
Here cp is not equal to sp because he sell the cloth at 10% loss,
100 + G/100 + x = true scale / false scale,
Here, overall gain G = 15 % and loss x = -10% (-ve for loss)
100 + 15 / 100 - 10 = 100/L = 90/115 x 100
= 78.25 cm.
Hence, option 3 is the correct answer.
