Question
The length of a plot is six times its breadth. A
playground measuring 192 square metres occupies half of the total area of the plot. What is the length of the plot?Solution
Using formula, Area = lb, Let breadth of plot = x metre  Length = 6x metre According to question, ⇒ 6x2/2 = 192 ⇒ x2 = (192 x 2)/6 = 64 ⇒ x= 64 metre Therefore, length = 6 x 8 = 48 metre       Â
30.01 × √1023 + 196 = ? 2 – 287
What value should come in place of question mark (?) in the following question. (You need not to calcualte the exact value)
?/647 = 226/ ?
? = 650.24 + 1124.97 – 14.992 Â
√2024.84 + (24.86% of 1999.81) - (3/8 of 800.15) = ?
- 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.)
1080.04 – 250.18 + 199.98 ÷ 20.06 = ?
81% of 1550 + 27² = ? + 1386 ÷ 22
(1.01) 0 + (2.02) 1 + (2.93) 2 + (4.04) 3 + (5.05) 4 = ?
Solve the following expression and calculate the approximate value.
1727.8 + 2196.75 + 3 × 11.8 × 12.9 × 24.75
2550.03 ÷ 74.98 x 49.9 = ? + 20.32
