Question
A seller marked an article 70% above its cost price and
sold it after allowing 20% discount. If he made a profit of Rs. 63, then find the difference between selling price and marked price of the article.Solution
Let the cost price of the article be Rs. β2xβ
So, marked price of the article = 2x Γ 1.7 = Rs. β3.4xβ
Selling price of the article = 3.4x Γ 0.8 = Rs. β2.72xβ
Profit = 2.72x β 2x = Rs. β0.72xβ
ATQ;
0.72x = 63
Or, x = 87.5
So, marked price of the article = 87.5 Γ 3.4 = Rs. 297.5
Selling price of the article = 87.5 Γ 2.72 = Rs. 238
Required difference = 297.5 β 238 = Rs. 59.5
(400.01% of 149.89) Γ· 49.97 = ?2 Γ· (95.98 Γ· 31.99)Β
`11(2/13)` + `5(2/11)` - `3(4/9)` = ?
What approximate value will replace the question mark (?) in the following?
29.99...
(4913)1/3 Β Γ 10.11 Γ 13.97 Γ· 20.32 = ?Β + 39.022
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
120.02% of 599.90 + (34.78/20.89) Γ (47.98) = ?2 β 10.022
6.992 + (2.01 Γ 2.98) + ? = 175.03
509.85 Γ· 15.05 + 210.16 β 18.06 Γ 5.95 = ?
124.88% of 60.101 + 18.09% of 849.87 β 22.12% of 1049.93= ? β 19.93
