Let the rate of interest r % per annum. According to the question, (40000 × 2 × r)/100 + (10000 × 4 × r)/100 = 6,000 ⟹ 800 r + 400 r = 6,000 ⟹ 1200r = 6,000 ⟹ r = 5% p.a.
39.9% of 1720 + 80.2% of 630 = 89.9% of 1280 + ?
(47.981% of 295) + (24.91% of 245) =?

49.99% of 5400 + 923=?
25.31% of 5199.90 + (19.9 × 17.11) + 46.021 =? + 168.98
75.22 of 219.98% + 359.99 ÷ 18.18 = ?
(1550.23 ÷ 30.98) + (864.32 ÷ 23.9) + 1724.11 = ?
1224.86% of √6399.98 = (399.99/4.99)% of (? ÷ 6.91 + 39.87)
14.232 + 19.98% of 629.99 = ? × 6.99
