In Champions league, Rohit scored an average of 120 runs per match in the first 3 match and an average of 140 runs per match in the last four match. What is Rohit’s average runs for the first match and the last two match if his average runs per match for all the five match is 122 and total number of matches are 5? 
» Explain it
A
Rohit’s average score in the first 3 exams = 120

Let the scores in the 5 exams be denoted by M1, M2, M3, M4, and M5

M1 + M2 + M3 = 120 × 3 = 360     .......(i)

Average of last 4 match = 140

⇒   M2 + M3 + M4 + M5  = 140
4

⇒ M2 + M3 + M4 + M5 = 560        ......(ii)

Average of all the exams
⇒   M1 + M2 + M3 + M4 + M5  = 122
5

∴   M1 + M2 + M3 + M4 + M5 = 122 × 5 = 610                    .......(iii)

From solving above equation, we get M1 + M4 + M5 = 300
 
Required average runs =  300  = 100
3

Hence correct option (A) is correct.

Ramesh kejriwal lent a sum of Rs.100 at simple interest of 6% p.a. for the first month, 12% p.a. for the second month, 24% p.a. for the third month and so on. What is the total amount of interest earned at the end of one year?
» Explain it
C
Principal= Rs.100

Rate of interest for first month = 6%

Interest = Rs. 6/12

Interest for second month = Rs. 12/12

The interest earned for the successive months is in the form of geometric progression.

Rs. 6/12, Rs. 12/12, Rs. 24/12 …………

a = Rs.6/12, r = (12/12)/ (6/12) = 2, where a is the first term and r is the common ratio of the series.

Sum of series =  a (rn – 1)
r – 1

  6 (212 – 1)      
=   12  =  6 (4096 – 1)
2 – 1 12

=   6  × 4095 = Rs.2047.5
12

Hence correct option (C) is correct.

Virat can do a piece of work in 24 days and Sachin can do the same work in 36 days. If Virat works for three days and got Rs. 3600, and the remaining work will completed by Sachin, then how much rupee Sachin earned
» Explain it
D
Assume total work = LCM (24, 36) = 72

If the entire work is 72 units, Virat can complete 3 unit per day, and Sachin can complete 2 unit per days 

In 3 days, Virat completes 9 units and got Rs.3600 i.e. Rs.400 per unit.

Remaining work = (72 – 9)unit = 63 unit

∴   Sachin earning = Rs.63 × 400 = Rs.25200

Hence correct option (D) is correct.

Shanghai Maglev and Harmony CRH 380A are two fastest train in world. Train Harmony CRH 380A whose length is three-fifth of that of train Shanghai Maglev crosses it travelling in opposite direction in a time which is 3/7 th of the time taken by Shanghai Maglev to cross it when travelling in same direction. Calculate the ratio of the speeds of Shanghai Maglev and Harmony CRH 380A.
» Explain it
B
Let L1, and L2 be the lengths of the trains Shanghai Maglev and Harmony CRH 380A respectively

Distance covered in each case = L1 + L2.

Let the speed of the train Shanghai Maglev = S1

Speed of the train Harmony CRH 380A = S2

L1+L2  =  3 ( L1 + L2 )  ⇒  S1 + S2  =  7
S1+S2 7 S1 - S2 S2 - S1 3

∴    S1  =  5     (by componendo and dividendo)
S2 2

∴   The ratio of the speeds of the two trains 5 : 2

Hence correct option (B) is correct.
5
An internet service provider company Century link marks up the cost price of a plan by 60% and offers a discount of 20%. He asks the customer to pay a service tax of 15% on the selling price. The customer refuses to pay the tax due to which the shopkeeper himself pays the service tax. Find his profit percentage
» Explain it
A
Let the cost price of the plan be P

Marked price = 1.6 P

Selling price = 0.8 (1.6P) = 1.28 P

Service tax = 0.15(1.28P) = 0.192P

Profit % =  (1.28P – 0.192P) – P  × 100% = 8.8%
P

Hence, option A is correct.
