Rate downstream = (x + 2) km/hr Rate upstream = (x – 2) km/hr According to the question, y/(x + 2) = 5 --- (i) y/(x – 2) = 11/2 --- (ii) On dividing equation (i) by (ii), (x – 2)/(x + 2) = 5/(11/2) = 10/11 11x – 22 = 10x + 20 x = 22 + 20 = 42 kmph

116.90 ÷ (77.81 ÷ 6.06) + 6.32 = (15.12% of ?) ÷ 4.652
14.12 × 21.98 + 25.22% of 195.99 = ? × 50.9
45.22% of (71.9 x 5.01) + 69.97 =?

Find the value of ‘x’ in the given expression:[144 + {2 × (13 ÷ 0.5 × 6 – 3) ÷ 4} – 6.5] = x
1587.9 + 9650.98 + 10612.8 =?3 - 2536.67
65.22 of 359.98% + 459.99 ÷ 23.18 = ?
(1560.23 ÷ 25.98) + (768.32 ÷ 23.9) + 1814.11 = ?
