Question
A pair of shoes is sold for Rs. 810 after two successive
discounts of 25% and 50%, respectively. If the cost price of the shoes is Rs. 1600, find the percentage by which the shoes is marked above its cost price.Solution
ATQ, Let the marked price of the shoes be Rs. x Therefore, selling price of the shoes = 0.75 × 0.5x = Rs. 0.375x According to the question, 0.375x = 810 Or, x = 2160 Therefore, percentage by which the shoes was marked up above its cost price = {(2160 – 1600)/1600} × 100 = 35%
Determine the value of ‘x’ if x% of 500 plus {1250 ÷ x of 10} × 5 equals 130
540240 ÷ 24 ÷ 25 =?
17.5% of 400 – 24% of 150 = ?
(-251 × 21 × -12) ÷ ? = 158.13
√(?) = (897 × 51) ÷ 1016.6
[∛(3375/19683  )- ∛(125/1728  )  ] ÷ ∛(64/729)  = ? - 3/8Â
?% of 120 × 3√343 = 42 × 20
What will come in the place of question mark (?) in the given expression?
? × 18 + 3072 ÷ 24 = 20% of 1900Â
Simplify the given expression:
[(2.3)3 + (15.9) ³ + (3.7) ³ – 3 × 2.3 × 15.9 x 3.7)] / [(2.3) ² + (15.9) ² + (3.7) ² – 2.3 ...
