Question
Some notebooks were distributed among (3x + 2) students
such that each student received 6 notebooks. If there had been 7 students more, then notebooks received by each student would have been 2 less. Find the value of ‘x’.Solution
According to the question, (3x + 2) × 6 = (3x + 2 + 7) × 4 Or, 18x + 12 = 12x + 36 Or, 6x = 24 Or, x = 4

- 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.)
{(23.65 × 35.12) ÷ 6.97} + 179.86 = ? × 14.76
1080.04 – 330.18 + 449.98 ÷ 15.06 = ?
? 2 + (39.99 × 10.99 + 7.01) - (39.99 × 2.99 2 + 21.99) = 21.99 × 23.01
