Question
Train X running at a speed of 34 km/hr crosses train Y
in 24 seconds. Find the speed of train Y (in km/hr), if the sum of the length of train X and Y is 700 meters and both trains running in the opposite direction. TYPE 46Solution
Let speed of train Y be 'a' km/hr. According to question, => 24(34 + a) × (5/18) = 700 => 816 + 24a = 2520 => 24a = 1704 => a = 71 km/hr
What will come in the place of question mark (?) in the given expression?
(63 - ?) ÷ 5 + √625 = 19 X (9 - 6)
- What will come in place of (?), in the given expression.
(4² + 6²) × 2 = ? What will come in the place of question mark (?) in the given expression?
(40/25) X 80 - ? = 45% of 300 - 5525.6% of 250 + √? = 119
1220 ÷ 61 ÷ 5 + 450 of 20% - 70 = √ ?
Simplify the expression:
(5x + 15) / (x² + 3x)
What will come in the place of question mark (?) in the given expression?Â
435 ÷ 29 X 792 ÷ 44 = √(? + 14) + 35 + 221 ÷ 17
...192.251 + 326.233 + 125.021 + 19.273 = ?
36% of 640 – 12.5% of 352 + 25% of 640 = ? – 48% of 432
Simplify the following expressions and choose the correct option.
18 * 15 - {3/5 of 250 + 72}
