Three persons A, B and C start travelling from city P at 4:00 a.m., 5:00 a.m. and 6:00 a.m. respectively. All the three reach the point Q simultaneously and continue beyond that point. C reaches the point R first and turns back immediately towards P. Thirty minutes after turning back, he crosses A.
Questions :
1.If the distance between P and Q is equal to the distance between Q and R, then the time at which all the three reach Q is
A.6:30 a.m.
B.7:00 a.m.
C.8:00 a.m.
D.7:30 a.m.
2.
If the distance between P and Q is equal to the distance between Q and R, then the time at which C crosses B for the second time is
A.7:40 a.m.
B.8:00 a.m.
C.8:20 a.m.
D.8:40 a.m.

A child was asked to add first few natural numbers (i.e. 1 + 2 + 3 + …) so long his patience permitted. As he stopped, he gave the sum as 575. When the teacher declared the result wrong, the child discovered he had missed one number in the sequence during addition. The number he missed was
a.Less than 10 b.10 c.15 d.More than 15
89y – 273x = 40
What is the sum of x and y if both x and y are natural numbers less than 100?
(a) 94 (b) 97 (c) 88 (d) Cannot be determined
