Question
Solution
3x2 – 5x + 1 = 0 then x2  + 1/9x2 divide equation by 3x = x – 5/3 + 1/3x = 0 = x + 1/3x = 5/3 = x2  + 1/9x2  = 25/9 – 2/3 = 19/9
- What will come in place of (?), in the given expression.
(56 × 3) + (480 ÷ 6) = ? 4.5 times 5/0.9× 35% of 240 =?
(115 × 17 × 3)/(23 × 51) + ?3 = √169
If A = 0.84181818... then what will be the difference between the numerator and denominator of the lowest fraction form of A?
30% of 2200 +’?’ x 50 – 1020 = 11x 306 + (√ 2250 ÷ 0.1) Â
5 × 14 + 100 ÷ 4 = 62 + ?
√64 of √225 = √(25 + ?) X 12
{5% of (20 × 25) + 6% of (30 ×35)} ÷ 11 = ?Â
