Directions (11-15): What should come in place of question mark (?) in the following given questions (just calculate the approximate value)?
Q11. 441.01 – 232.99 + 1649.99 = ? + 1225.92
⇒ 1858 ≈ ? + 1226
⇒ ? ≈ 1858 – 1226 ≈ 632 ≈ 630
Q12. 23.001 × 18.999 × 7.998 = ?
Q13. 73.99% of 1299 + 9.98% of 1899 = ?
Q15. 89.988% of 699.9 + 50.002% of 999.99 – 170.015 = ?
