"Rs268",
"Rs286",
"Rs296",
"Rs266"
] | D | Let cost price was X.
SP = X + 14% of X = 1.14X.
If CP and SP were Rs. 132 less, the profit would be (14 +12)%.
New, CP = ( X - 132)
SP = 1.14X - 132
SP - CP = 26% of (X - 132)
1.14X - 132 - X + 132 = [26*(X -132)]/100
0.14X * 100 = 26X – 3432
14X – 26X = - 3432
12X = 3432
X = 286.
So, CP was Rs 286.

The price of rice falls by 20%. How much rice can be bought now with the money that was sufficient to buy 20 kg of rice previously? | [
"30 kg",
"None",

A shopkeeper sells his goods at cost price but uses a faulty meter that weighs 700 grams. Find the profit percent. | [
"100/13%",
"None of these",
"100/19%",
"100/7%"
] | D | Explanation:
(100 + g) / (100 + x) = True measure / Faulty measure
x = 0
true measure = 1000
faulty measure = 700
100 + g / 100 + 0 = 1000 / 700
100+g = 10/7*100
g = 300/7 %

Tom runs everyday for exercise and running burns 500 calories/mile. If Tom wants to lose 10 pounds, how many miles for how many days does Tom have to run in total. (Assume it takes 3000 calories to lose 1 pound of weight) | [
"15 miles for 10 days",
"1 mile for 20 days",
