Question
A shopkeeper claims to incur a loss of 20% but uses a
weight of 640 grams in place of 1kg  If the CP of the rice is Rs 80/kg , what will be the % of actual gain/loss ?Solution
ATQ, We can say that 20% is = 20/100 = 1/5 Then C.P will be = 5, and S.P will be = 5 – 1 = 4 Therefore, (S.P/C.P) = 4/5 Then = (4/5) x (1000/640) = 5/4 Hence, profit % will be = (1/4) x 100 = 25%
115.98 + 109.01 + (√575 - 17) X 20.09 - 204.89 + 38.03 = ?
25.02% of 460.02+?% of 300.02=295.21
What approximate value will replace the question mark (?) in the following?
√40...
45.22 of 499.98% + 399.99 ÷ 20.18 = ?
118.95 – 24.10 + (91.90 ÷ 22.89 × 12.14) = ?
47.87% of 749.76 + 35.11% of 399.76 = √? + 23.15 × 20.87
32.052- 22.03 x 24.199 - 15.18 x 11.04 = ?
? = 49.97% of 38.09% of 1998.95
125.9% ÷ 9.05 x 99.98 = ? - 69.97 × √324.02 ÷ 5.98
