Let distance= x km, Rate upstream = 36 - 12 = 24 km/hr Rate downstream = 36 + 12 = 48 km/hr. ∴ Time taken upstream= x/24 and Time taken downstream= x/48 ∴ x/24 + x/48 = 3 ⇒ 3x/( 48) = 3 ⇒ x = 48 km.
(100.01% of 44.89) ÷ 14.98 = √? - √48.98
9.89 x 4.99 + 2.01 x 49.89 = ?% of 299.69
431.98 + ? – 15.04 = 864.93 – 368.01
56.02% of 1499.98 + 64.04% of 2501.01 = ? + 25.05 × 49.98 + 6.063
³√? × 33.97 + 59.99 × 28.9 – 48.98 × 21.42 = 1085.344
18.002 × 109.995 + 1499.996% of 450.08 + 12.005 % of 2999.997 = ? × 30.008 × 25.009
47.87% of 749.76 + 35.11% of 399.76 = √? + 23.15 × 20.87
15.001% of 799.99 - 3/11% of 1099.99 + 111.002 = ?
(48/16)2 × 50/50 ÷ 50/800 = ?
