Question
The cost of 3 kg of rice is Rs. 180. The cost of 8 kg of
rice is equal to that of 5 kg of pulse. The cost of 15 kg of pulses is equal to that of 2 kg of tea. The cost of 3 kg of tea is equal to that of 6 kg of walnuts. What is the cost (in Rs.) of 10 kg of walnuts?Solution
3 kg. Rice = Rs. 180 1 kg. Rice = Rs. 60 8 kg rice =480 Then ATQ- 5 kg. pulse = 8 × 60 = Rs. 480 15 kg. Pulse = 3× 480= Rs.1440 2 kg. Tea = Rs.1440 1 kg tea =720 3 kg. Tea = Rs.2160 = 6 kg. walnuts 6 kg. walnuts = 2160 1 kg walnuts =360 Then 10 kg. walnuts 360×10 = 3600rs
Evaluate: 360 ÷ [ {18 − (6×2)} × 5 ] + 72 − 33
(43)² - (28)² + (32)² = ?% of 2500
Evaluate:
√729 + √49 - √16 + 1/√64
What will come in place of (?) in the given expression.
12.5 + 7.75 - 3.6 = ?62 of 8 - 320 ÷ 4 = ?3 + 200
2(1/3) + 2(5/6) – 1(1/2) = ? – 6(1/6)
What will come in the place of question mark (?) in the given expression?
30% of 520 + 16% of 1500 = ? + 244
60% of 120 – ?% of 64 = 20% of 200
35% of 840 + 162 = ? – 25% × 300
20% of 240 + 18% of 200 = ?
