Question
Two cyclists start from villages R and S which are 234
km apart. One starts from R at 6:45 a.m. at 36 km/h. Another from S at 7:45 a.m. at 54 km/h towards R. When will they meet?Solution
Time gap = 1 hour β Distance = 36 Γ 1 = 36 km
Remaining = 234 β 36 = 198 km
Relative speed = 90 km/h
Time = 198 / 90 = 2.2 hrs = 2h 12m
Meeting time = 7:45 a.m. + 2h 12m = 9:57 a.m.
What will come in the place of question mark (?) in the given expression?
? = 90% of 25% of (40 Γ 200) + 300
30% of 40% of 120% of 3500 = ? Γ 63
`(256/6561)(1/4) = ?`
What will come in the place of question mark (?) in the given expression?
β144 X β324 + ? = 83 + 31 X β16
(34.88% of 699.79) + 40.030 × 17.88 of 11.86 + 16.21 =? + (7.22)²
72.5% of 400 – 23.25% of 1020 = 105% of ?
5.45% of 1854 – 37.5% of 1096 = ? – 48% of 630
800 + 900 X (3)-2 - ? = 25 X 60 Γ· 2Β
? = 6.25% of 240 + 252 + 172 β 16 Γ 17
1500 Γ· 15 + 1000 Γ· β100 + ? = 250 * 3
