Answer: (b)

p = 260

Lokesh passing % = ${312 - 260}/260$ × 100 = 20%

The total amount the person paid, including the sales tax was Rs.136.75. What was the price of the article Y before sales tax?

Answer: (b)

ATQ

Let cost of X = x

Then, cost of Y = 130 – x

Now,

$x + (130 – x) 109/100 = 136.75$

100x + 14170 – 109x = 13675

9x = 495 ⇒ x = 55

Thus, rate of article y = (130 – x)

= 130 – 55 = Rs. 75
