The average weight of a group of five persons, A, B, C, D, and E is 80 kg. If another person K joins the group then the average weight of the group is decreased by 6.5 kg, then find the weight of K.
Total weight of A, B, C, D, and E together = 80 × 5 = 400 kg Weight of K = 73.5 × 6 – 400 = 441– 400 = 41 kg

32.052- 22.03 x 24.199 - 15.18 x 11.04 = ?
31.98% of 224.99 = 24.98% of ? + 9.91% of 499.99
15.63% of 174.99 + √? = 139.98% of 24.98
564.932 + 849.029 – 425.08 = 612.095 + ?
244.98% of 189.98% of 599.99 + 199.98 = ?
16.22 × 12.99 + 142.15 = ?
{44.78% of (11.67 × 54.78)} ÷ 2.65 = ? + 19.25
19.92 × (52.065/260.07) × (45.09% of 359.87) =?
