Question
Which of the following property of soil can’t be
changed by any means?Solution
Texture of soil cannot be changed.
36% of 640 – 12.5% of 352 + 25% of 640 = ? – 48% of 432
If (7a + b) : (7a - b) = 7:3, then find the value of a:b?
26 2 – 13% of 400 + (529 ÷ 23 2 ) = ? 2Â
What value should come in the place of (?) in the following questions?
?2 = 240 * √25 + 38 * 5 - 94
7(1/5) – 3(1/4) + 8(3/4) = ?
(2/5)(32% of 4500 – 440) = ? × 8
{(8× 8 + 3 × 39) - 620 ÷ 20} = ?

8(3/4) + 5(1/6) – 4(3/4) = ?
15 × 35 ÷7 + 60% of 300 =?
