Question
There are three commodities –the first commodity has a
negative price, at −1 per unit; the second commodity is priced at +1 per unit while the third is priced at +2 per unit. Income of the person is Rs. 100 per day. Then which one of the following is not true?Solution
Solution If the consumer is consuming zero units of both first and second commodity and 60 units of third commodity, then it means that to consume 60 units of third commodity he will need Rs 120 (60× 2). Since the income of the consumer is only Rs. 100 per day, therefore he will not be able to consume 60 units with his given income. Therefore (c) is definitely not true.
(18.31)2 – (13.68)2 + (2344.20 + 82.32) ÷ ? = 229.90
- 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.)
24.01 X 24.99 - ?% of 599.96 = 14.92 X 8.12
20.11 × 6.98 + 21.03 × 6.12 – 37.95 + 92.9 × 5.02 =?
Direction: Solve the following expression and calculate the approximate value.
(5.78 + 3.12)² + 8.2² + 2 × 8.1 × (5.9 + 3.2)
...Find the approximate value of Question mark(?). No need to find the exact value.
(55.96 × 4.01) ÷ 7 + √(120.81) × 3 – 10% of 199.99 = ?<...
888.191 + 2.0001 X 7.961= ?
80.09 * √144.05+ ? * √224.87 = (2109.09 ÷ √1368.79) * 19.89
- 44.83% of 799.88 + (84.12 X 14.98 ÷ 62.87) = ?² + 55.65
The greatest number that will divide 398,436, and 542 leaving 7, 11, and 15 as remainders, respectively, is:
