Question
Cost of two types of pulses is Rs.25 and Rs, 30 per kg,
respectively. If both the pulses are mixed together in the ratio 2:3, then what should be the price of mixed variety of pulses per kg?ÂSolution
(30 – x)/(x – 25) = 2/3 90 – 3x = 2x – 50x 5x = 140 x = 28 Therefore, price of mixed variety of pulses = Rs 28 per kgÂ
- Find the value of the expression:
15 + 10 – 6 × [20 + 8 – 2 × (50 – 35)] (? + 180 + 13 × 6) ÷ 20 + 3.5 × 512 (1/3) = 82
√10000 × √8100 - (50)² = √(?) + (80)²
5/2 of 5/6 of 12/5 of 54 % of 5250 = ?
What will come in the place of question mark (?) in the given expression?
(? ÷ 16) = (20 ÷ ?) X 20322 – 182 + 11 × 24 = ?
What will come in the place of question mark (?) in the given expression?
59.92 × 15.11 + √4224 = ? + 144.9Â
What will come in the place of question mark (?) in the given expression?
(87 + 79) X √9 - 298 = ? + √3600
5121.3 × 641.8 ÷ 80.5 = 8?
