Every month a man consumes 25 kg rice and 9 kg wheat. The price of rice is 20% of the price of wheat and thus he spends total Rs. 350 on the rice and wheat per month.

"24%",
"40%",
"36%",
"25%"
] | C | Solution: Let the price of wheat is x per kg. Then price of wheat will be 5x per kg.
Expenditure on rice = 25*x = 25x.
Expenditure of wheat = 9*5x = 45x.
Total cost,
25x + 45x = 350.
70x = 350.
x = 5.
Hence, price of Rice = Rs. 5 per kg.
Price of wheat = 25 per kg.
Now, price of wheat = 25 ---- 20% ↑----> Rs. 30 per kg... | AquaRat_train |

A 270 m long train running at the speed of 120 kmph crosses another train running in opposite direction at the speed of 80 kmph in 9 seconds.What is the length of the other train? | [
"240 m",
"350 m",
"260 m",
"230 m"
] | D | speed of first train= (120 * 5/18)m/sec
= 100/3 m/sec
speed of other Train= (80 * 5/18)m/sec
= 200/9 m/sec
time to cross each other= 9 sec
Let x be the length of 2nd train
therefore 9 = (270+ x)/(100/3 +200/9)
500 = 270 + x
230m = x
