Question
A shopkeeper sells a homogeneous mixture of A and B at a
rate of Rs 320 per kg. Find the profit percentage of the shopkeeper. Statement I : he brought A at the rate of Rs 280 per kg. Statement II : He bought B at Rs 18 higher than the rate of A per kg. Statement III : He brought B at the rate of Rs 190 per kg.Solution
We don’t know the ratio in which the mixture is mixed. So we cannot find the CP and hence profit.
193. 69 + 200.09 – 512.96 + 312.09 =?
{(300 ÷ 15)% of 1500} ÷ 6 = ? + 120Â
Simplify the following expressions and choose the correct option.
[(2/3 of 270) ÷ 9] + [(5/6 of 96) ÷ 8] = ?
125% of 129 ÷ 43 × 28 ÷ 7 = ? ÷ √16
31% of 1900 - ? = 73
(160 × 12 - 13 × 20)/(120 × 2 + 2 × 35 + 2 × 11) = ?
Find the value of ‘x’ if (5 × 196 – 340 ÷ 17) ÷ 20 = √1600 – x.
? = (22% of 25% of 60% of 3000) + 21
If x + y + 3 = 0, then find the value of x3 + y3 – 9xy + 9.
- Find the value of:
35% of [150% of (45 + 15) + 150] ÷ 75 × 80
