Question
The profit earned on selling an item is 25%. If the cost
price of the item was 20% less, and the selling price of the item was Rs. 30 more, then the profit earned would be 60%. Find the absolute reduction in the cost price of the item.Solution
ATQ,
Let the initial cost price of the item be Rs. 100x
So, selling price of the item = 100x × 1.25 = Rs. 125x
So, new cost price of the item = 100x × 0.8 = Rs. 80x
And new selling price of the item = Rs. (125x + 30)
ATQ:
80x × 1.60 = 125x + 30
Or, 128x = 125x + 30
Or, 3x = 30
So, x = 30 / 3 = 10
Required reduction = 100x – 80x = 20x = 20 × 10 = Rs. 200
What value should come in place of (?) question mark in the given expression.
17 × 15 − 96 ÷ 8 + 6² = ?
Evaluate: 144 ÷ 12 × 6 + 35 − 4²
What will come in the place of question mark (?) in the given expression?
21 × 18 + ? – 19 × 15 = 25 × 24
2916 ÷ 54 = ? + 27
√324 + √484 + 63 = ?2
What will come in the place of question mark (?) in the given expression?
{(2/15) + (12/25)} of 375 + 190 = ?% of 375
- What will come in place of the question mark (?) in the following questions?
100−[20+4×5]=? (72 × 52 + 1555 )/(79+60) = 2000 ÷ ?
72 × 2 = ? + 104 – 14
672 ÷ 28 × 24 + 363 – 309 =?
