Question
If x + y + z = 0, then what is the value of
(3y2 + x2 + z2)/(2y2 – xz)?Solution

What will come in the place of question mark (?) in the given expression?
{(3600 ÷ 20 of 15) × 40 + 300} = ? % of 1500
- What will come in place of (?), in the given expression.
125% of 96 + 33% of 300 = ? 5/12 of 216 + 3/4 of 120 – 2/5 of 140 = ?
Simplify: 3/4 + {5/6 ÷ (2/3 − 1/6)} − 7/8
Solve the following:
1500 ÷ (9 × 18 ÷ 6 × 3 – 45) ²
?² = 37% of 800 – 14 × 18+ 5! - 20
What should come in place of (?) question mark in the given expression.
1440 ÷ (6 × 4) + 2⁵ = ?
[{70 + (40 - 22) ÷ 3} ÷ 4] = ?
