Sign in nowVolume of the earth dug out = 8×7 ×5 = 280 m³ The upper surface area of the field = 8×7 = 56 m² Total surface area of the field = 51×30 = 1530 m² Remaining area of the field = (1530 – 56) = 1474 m² ∴ Rise in the level of the remaining part of the field = 280/1474m = (28/1474) × 100cm= 18.99 cm ∼19cm
What will come in the place of question mark (?) in the given expression?
45% of (√6400 × 5) = ? + 111
50% of (22 x 15) + 205 = ?
(560 ÷ 32) × (720 ÷ 48) = ?
1780 – 60 ÷ 4 x 80 = ?
The value of (40 + 3/4 of 32) /[37 + 3/4 of (34-6)] is:
Find the simplified value of the following expression:
[{12 + (13 × 4 ÷ 2 ÷ 2) × 5 – 8} + 13 of 8]
(√ 121 x 41) + (3√343 x √289 ) = ? x 19
62 + 43 + 625(1/4) - ? = 102
