Question
What is the area of the square? I. The diagonal
of the square is the 6√3m. II. The perimeter of the square is 48m. Each of the following questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give answer.Solution
From I Area of the square = 1/2 d2 = 1/2 (6√3)² = 1/2 × 36 × 3 = 54m² From II Perimeter of the square = 48m Side = 48/4 = 12m ∴ Area of the square = (12)² = 144m² Hence, the question can be answered either from statement I or from statement II.
81% of 1550 + 27² = ? + 1386 ÷ 22
510.11 ÷ 16.98 × 5.14 – 119.9 = √?Â
(0.89 3 + 1.64 3 +2.76 3 ) ÷ 5.89 = ?
√3601 × √(224) ÷ √102 = ?
? = 540.24 + 1022.97 – 11.992 Â
What approximate value will replace the question mark (?) in the following?
18.99...
?% of 1499.89 + 54.14 × 8 = 25.05% of 5568.08
(289.89 + 59.98) X 2.25 = ? X 49.66
? × [(16.87) 2 – (6.98) 2 ] = 5.04× 191.11
? = 49.83% of 39.72% of (45.011.99 – 4.98 2.04)
