On dividing a number by 357, we get 39 as remainder. On dividing the same number by 17, what will be the remainder?

Detailed Solution for SBI PO Prelims Mock Test - 1 - Question 2

Let x be the number and y be the quotient. Then, x = 357 × y + 39
= (17 × 21 × y) + (17 × 2) + 5
= 17 × (21y + 2) + 5
So, required number = 5

SBI PO Prelims Mock Test - 1 - Question 4

The LCM of two numbers is 495 and their HCF is 5. If the sum of the numbers is 100, then their difference is 

Detailed Solution for SBI PO Prelims Mock Test - 1 - Question 4

Let the numbers be x and (100-x)
Then, x (100-x) = 5 × 495  

x2-100x + 2475 = 0
(x-55) (x-45) = 0
x = 55 or x = 45
Therefore, the numbers are 45 and 55.
Required difference = (55-45) = 10

SBI PO Prelims Mock Test - 1 - Question 5

A child has three different kinds of chocolates costing Rs.2, Rs.5 and Rs.10. He spends total Rs.120 on the chocolates. What is the minimum possible number of chocolates, he can buy, if there must be atleast one chocolate of each kind?

SBI PO Prelims Mock Test - 1 - Question 13

The distance between two cities A and B is 330 Km. A train starts from A at 8 a.m. and travel towards B at 60 km/hr. Another train starts from B at 9 a.m and travels towards A at 75 Km/hr. At what time do they meet?

Detailed Solution for SBI PO Prelims Mock Test - 1 - Question 13

Suppose they meet x hrs. after 8 a.m. then
(Distance moved by first in x hrs.) + = 300
[Distance moved by second in (x-1) hrs.]
Therefore 60x + 75 (x-1) <=> 330
x = 3
So, they meet at (8 + 3) i.e. 11 a.m.

SBI PO Prelims Mock Test - 1 - Question 15

 

BH is perpendicular to AC. Find the length of BC.

Detailed Solution for SBI PO Prelims Mock Test - 1 - Question 15

BH perpendicular to AC means that triangles ABH and HBC are right triangles. Hence
tan (39°) = 11/AH or AH = 11/tan (39°)
HC = 19-AH = 19-11/tan (39°)
Pythagora’s theorem applied to right triangle HBC :11+ HC2 = x2  Solve for x and substitute HC : x = sqrt [112 + (19-11/ tan(39°)2 ] = 12.3

SBI PO Prelims Mock Test - 1 - Question 16

Find the lengths of the other two sides of a right triangle if the length of the hypotenuse is 8 inches and one of the angles is 30°. 

Detailed Solution for SBI PO Prelims Mock Test - 1 - Question 16

This is a right triangle with a 30° angle so it must be a 30°-60°-90° triangle.
You are given that the hypotenuse is 8. Substituting 8 into the third value of the ratio n: n√3 :2n,
we get that 2n = 8 n = 4
Substituting n = 4 into the first and second value of the ratio we get that the other two sides are 4 and 4√3
The lengths of the two sides are 4 inches and 4√3 inches.

SBI PO Prelims Mock Test - 1 - Question 17

A man takes 3 hours 45 minutes to row a boat 15 km downstream of a river and 2 hours 30 minutes to cover a distance of 5 km upstream. Find the speed of the river current in km/hr.

Detailed Solution for SBI PO Prelims Mock Test - 1 - Question 17

Let Speed of Boat and stream be b and s respectively.

We know:

15/(b+s)=15/4 ............Eqn 1 (From the downstream condition as distance/speed is equal to time)

Also 5/(b-s)=5/2 .............Eqn 2

Therefore, solving Eqn 1 and Eqn 2, we get:

b+s=4

b-s=2

Therefore, further solving gives b=3 and s=1

Hence, Solution is A.

SBI PO Prelims Mock Test - 1 - Question 30

Directions (Q.71-80) Read the following passage carefully and answer the questions given below it. Certain words have been printed in italic and Underline to help you to locate them while answering some of the questions.

Banking sector reforms in India were introduced in order to "improve" efficiency in the process of financial intermediation. It was expected that banks would take advantage of the changing operational environment and improve their performance. Towards this end, the Reserve Bank of India initiated a host of measures for the creation of a competitive environment. Deregulation of interest rates on both deposit and lending sides imparted freedom to banks to appropriate price their products and services. To compete effectively with non-banking entities, banks were permitted to undertake newer activities like investment banking, securities trading and insurance business.

This was facilitated through amendments in the "relevant" acts which permitted PSBs to raise equity from the market up to threshold limit and also enabling the entry of new private and foreign banks. This changing face of banking led to an erosion of margins on traditional banking business, promoting banks to search for newer activities to "augment" their free incomes.

At the same time, banks also needed to devote focused attention to operational efficiency in order to contain their transaction costs. Simultaneously with the deregulation measures prudential norms were instituted to strengthen the safety and soundness of the banking system. Recent internal empirical research found that over the period 1992-2003, there has been a discernible improvement in the efficiency of Indian banks. The increasing trend in efficiency has been fairly uniform, irrespective of the ownership pattern. The rate of such improvement has, however, not been sufficiently high. The analysis also "reveals" that PSBs and private sector banks in India did not differe significantly in terms of their efficiency measures. Foreign banks, on the other hand, recorded higher efficiency as compared with their Indian counterparts.

 

Q.Prudential norms were initiated in the banking sector with a view to
