Question
A man takes a total of 5 hrs 30 min by walking to a
certain place and coming back by cycle. He would have gained 2 hrs 30 min by cycling both the ways. The time he would take to walk both ways isSolution
C+W = 5hrs 30 min ---(1) C+C = 5 hrs 30 min - 2 hrs 30 min = 3 hrs 2C = 3 hrs So C = 1hr 30 min ---(2) By equation (1) & (2), we will get, W = 5 hrs 30 min - 1 hr 30 min = 4 hrs So W+ W = 4+4 = 8hrs
What will come in the place of question mark (?) in the given expression?
(12.09)2 × 5.98 ÷ 26.95 = ? + 25Â
√441 * 7 – 10% of 250 + ? = 140% of 120

30% of 8/5 × 5/7 × 2870 =?
1231 + 1312 + 2113 – 3211 = ?
{(3/8) + (5/6)} × 120 – 53 = ?Â
What will come in the place of question mark (?) in the given expression?
23 X 35 - ? = (132 + 16) X 3 + 25
56 × 18 + ? × 21 – 49 × 12 = 63 × 26Â
- Evaluate: 168 ÷ 12 × 5 + 190 – 20% of 450
