Question
A man running at the speed of 4 kmph was over taken by
the train moving with the speed of 76 kmph in 32 seconds. Find the length of train. TYPE 6Solution
According to the question, Let length of train be βxβ m. => (Speed of train β Speed of man) = Length of train/Time => (76 - 4)Γ (5/18) = x/32 => 20 = x/32 => x = 640 Length of train is 640 meter.
√3598 × √(230 ) ÷ √102= ?
15% of 2400 + (β 484 β β 256) = ?
(13)2Β - 3127 Γ· 59 = ? x 4
6269 + 0.25 × 444 + 0.8 × 200 = ? × 15
...(53 + 480 Γ· 4)% of 20 = ?% of 70
Find the simplified value of the following expression:
62 + 122 Γ 5 - {272 + 162 - 422}
(15 Γ 225) Γ· (45 Γ 5) + 480 = ? + 25% of 1240
β [? x 11 + (β 1296)] = 16
11 Γ 25 + 12 Γ 15 + 14 Γ 20 + 15 = ?
