Question
Rahul bought two articles for Rs. 9,000. He sold one of
them at a profit of 30% while the other at a loss of 10%. If he earned an overall profit of 8% on selling both articles, then find the cost price of the article which is sold at loss of 10%.Solution
ATQ, Let cost price of the article sold at a profit of 30% = Rs. x Cost price of the article sold at a loss of 10% = Rs. (9000 β x) ATQ, (1.30 Γ x) + {0.90 Γ (9000 β x)} = 1.08 Γ 9000 Or, 1.30x + 8100 β 0.90x = 9720 Or, 0.40x = 1620 So, x = 4050 Therefore, cost price of the article sold at a loss of 10% = 9000 β 4050 = Rs. 4,950
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.)...
2720.03 Γ· 79.98 x 39.9 = ? + 40.32
β2401 Γ (β2116 Γ· 23) Γ 21 Γ· 3 = ?
29.98% of 549.99 = ? - 254.97 + 79.98% of 74.99Β
What approximate value will come in place of the question mark (?) in the following question?
(1963.33 Γ· 6.5 - 193.99)/? = 753.02 Γ·Β 26.98
63.981 + 64.001 + 65.08019 + 63.11112 =?
`sqrt(1297)` + 189.99 =?
[(2/3 of 599.77) + (39.69% of 450.14)] Γ· [(5/8 of 399.79) - β120.91] = ?
44.78% of 715.62 + 1785% of 42.98 = ?
