The minute hand of clock is √21 cm long. The area described by a minute hand on the face of the clock between 7 am and 7.05 am is
Given that length of minute hand of clock is √21 cm
Angle described by the minute hand in 60 minutes = 360^{o}
Angle described by the minute hand in 5 minutes = 360/60 x 5 = 30^{0}
We know that Area of sector = θ/360 x πr^{2}
In what time will Rs. 500 give Rs. 50 as interest at the rate of 5% per annum simple interest?
SI = 50
P = 500
R = 5% pa.
In questions below, equations have become wrong due to wrong orders of signs. Choose the correct order of signs from the alternative given.

2 Pipes can fill a tank in 20 and 24 minutes respectively and a waste pipe can empty 3 gallons per minute. All the three pipes working together can fill the tank in 15 minutes. The capacity of the tank is
Work done by the waste pipe in 1 minute = 1/15  ( 1/20 + 1/24 )
= ( 1/15  11/120 )
=  1/40
[ve sign means emptying]
∴ Volume of 1/40 part = 3 gallons
Volume of whole = (3 x 40) gallons = 120 gallons
In which country, a new endangered flowering plant species named ‘Primula Zhui’ has been discovered by its scientists?
4 x 96 + x = 1420  260
⇒ 384 + x = 1160
⇒ x = 776
A is 30% more efficient than B. How much time will they, working together, take to complete a job which A alone could have done in 23 days?
Ratio of times taken by A and B = 100 : 130 = 10 : 13
Suppose B takes x days to do the work
Then, 10 : 13 :: 23 : x
⇒ x = ( 23 x 13/10 )
⇒ x = 299 10
A's 1 day's work = 1/23 :
B's 1 day's work = 10/299
(A + B)'s 1 day's work = ( 1/23 + 10/299 ) = 23/299 = 1/13
Therefore, A and B together can complete the work in 13 days
Trains, A and B are travelling on the same route heading towards the same destination. Train B has already covered a distance of 220 km before train A started. The two trains meet each other 11 hours after the start of train A. Had the trains been travelling towards each other (from a distance of 220 km), they would have met after one hour. What is the speed of train B in km/hr?
Let the speed of train A = x
and the speed of train B = y
⇒ Relative speed (same direction) = (x + y) kmph
and relative speed (opp. direction) = (x  y) kmph
⇒ 1(x  y) = 220] x 11
11(x + y) = 220
⇒ 11x  11y = 2420 .....(1)
11x + 11y = 220 .....(2)
Solving equation (1) and (2) we get
22x = 2640
⇒ x = 120 kmph
⇒ y = 220  120 = 100 kmph
The distance between 6.00 AM and 3.15 P.M. by the tip of the 12 cm long hour hande in a clock is
Angle covered from 6 A.M. to 3.15 P.M.
Length of hour hand = 12 cm
i.e., r = 12 cm
Each of the following questions consists of two sets of figures. Figures 1, 2, 3 and 4 constitute the Problem Set while figures A, B, C, D and E constitute the Answer Set. There is a definite relationship between figures 1 and 2. Establish a similar relationship between figures 3 and 4 by selecting a suitable figure from the Answer Set.
In the following problem, out of the five figures marked 1, 2, 3, 4 and 5, four are similar in a certain manner. However, one figure is not like the other four. Choose the figure which is different from the rest.
In the following questions, select a figure from amongst the four alternatives, which when placed in the blank space of fig. (X) would complete the pattern.
A, B, C, D, E, F, G and H are sitting round the circle and are facing the centre:
(i) A is second to the right of E who is the neighbour of C and G.
(ii) D is not the neighbour of A ?
(iii) G is the neighbour of F
(iv) B is not between D and H. H is not between F and D.
Q. What is the position of D?
Answer these question based on the table given below .
