Question
What is the total cost of painting a conical flask at
the rate of Rs. 60 per square metre? Statement I : The radius and the height of the flask are 42 m and 36 m respectively Statement II: The area of the base of Flask is 462 sq. m and its height is 21 m. In each of the following questions, a question and two statements I and II are given. You have to decide whether the date given in the statements are sufficient to answer the question or not.Solution
From statement I, r = 42 m, h = 36 m, so cost of painting = 60 × πrl From II: pi × r × r= 462, so r can be calculated, h = 21 m, so I =pi ×  r ×  l, so I can also be calculated. cost of painting = 60 × πrl
12.052 + 36.15 × 25.45 – 124.15 × 15.05 = ? × 8.08 – 64.32 × 15.98
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.)...
(48.89 ÷ 7.08) × (35.96 ÷ 4.11) + (9.02 × 1.99) = ?
35.05% of 14.87 × (13.02 – ?) + 30.19 = 188.7
40.02% of 1220.05 = ?2 + 29.09 × 7.99
√2401 × (√2116 ÷ 23) × 21 ÷ 3 = ?
49.99% of 639.99 + 159.98% of 49.99 = ?2
480 ÷ 10 + 18 % of 160 + ? * 9 = 60 * √36
(24.98)2 = ?2Â + (14.99)2
1449.98 ÷ 50.48 × 10.12 = ? × 2.16
