Answer»

(80.0003% of 1601.73) + (75.123% of 1003.158) + 1000 - (50.82% of 3005.72) × 2.0007

Using BODMAS rule,

⇒ (80% of 1600) + (75% of 1000) + 1000 - (50% of 3000) × 2,

⇒ (80 × 16) + (75 × 10) + 1000 - (50 × 30) × 2, (SIMPLIFYING ‘brackets’)

⇒ 1280 + 750 + 1000 - 1500 × 2,

⇒ 3030 - 3000,

⇒ 30

∴ ? = 30
