Those maths are important for bank recruitment test. I have given the shortcut technique to solve those maths. I hope you will practice those maths. If you want the original solve of any particular math then write your requirement in the comment section. I will try my best to give you the solve.

1)
If
a merchant offers a discount of 30% on the list price, then she makes a loss of
16%. What % profit or % loss will she make if she sells at a discount of 10% of
the list price?

a)
6.25% loss

b)
6% loss

c)
0.8% profit

d)
8% profit

**Correct Answer (d) 8% profit**

**Shortcut Solve:**120X30% =36; 120-36=84=16%; 120X10%=12; 120-12=108; so 8% Profit.

2) A merchant marks his goods up by
60% and then offers a discount on the market price. If the final selling price
after the discount results in the merchant making no profit or loss, what was
the percentage discount offered by the merchant?

a)
60%

b)
37.5%

c)
40%

d)
Depends on the cost price

**Correct Answer (b) 37.5% discount**.

**Shortcut Solve**: 160X37.5 = 60; Product Price 160-60 = 100

3)
Rs.432 is divided amongst three workers A, B and C such that 8 times A’s share
is equal to 12 times B’s share which is equal to 6 times C’s share. How much
did A get?

a)
Rs.192

b)
Rs.144

c)
Rs.133

d)
Rs.128

**Correct Answers (b) Rs.144.**

**Shortcut Solve:**LCM 8:2:6 =24; 24/8:24/12:24/6 = 3:2:4; 3x+2x+4x = 432; 3x= 432; x = 48; so A gets 3X48 = 144

4)
The monthly incomes of A and B are in the ratio 4 : 5, their expenses are in
the ratio 5 : 6. If 'A' saves Rs.25 per month and 'B' saves Rs.50 per month,
what are their respective incomes?

a) Rs.400
and Rs.500

b) Rs.240 and Rs.300

c) Rs.320 and Rs.400

d) Rs.440 and Rs.550

b) Rs.240 and Rs.300

c) Rs.320 and Rs.400

d) Rs.440 and Rs.550

**Correct Answer (a) Rs. 400 and Rs. 500**

**Shortcut Solve:**4x-5y = 25; x = 25+5y/4; 5x-6y=50; 5X25+5y/y=50; y=75; x= 25+5XZ75/4; x = 100; Income 4X100 = 400 and 5 X 100 = 500.

5)
The monthly salaries of two persons are in the ratio of 4:7. If each receives
an increase of Rs.25 in the salary, the ratio is altered to 3: 5. Find their
respective salaries.

a) 120
& 210

b) 80 & 140

c) 180 & 300

d) 200 & 350

b) 80 & 140

c) 180 & 300

d) 200 & 350

**Correct Answer (d) 200 &350**

**Shortcut Solve**: 4x+5y/7x+25 = 3/5; 5(4x+25) = 3 (7x + 25); 20x + 125 = 21x + 75; x = 50; so Salary 4X50= 200 and 7X50 = 350

6)
The present ages of A and B are as 6 : 4. Five years ago their ages were in the
ratio 5 : 3. Find their present ages.

a) 42,
28

b) 36, 24

c) 25, 15

d) 30, 20

b) 36, 24

c) 25, 15

d) 30, 20

**Correct Answer ( d) 30, 20**

**Shortcut Solve**: 6X5 = 30; 4X5 = 20 so 30, 20; 30-5: 20-5; 25:15; 5:3

7)
A 20 litre mixture of milk and water
contains milk and water in the ratio 3 : 2. 10 litres of the mixture is removed
and replaced with pure milk and the operation is repeated once more. At the end
of the two removal and replacement, what is the ratio of milk and water in the
resultant mixture?

a) 17
: 3

b) 9 : 1

c) 3 : 17

d) 5 : 3

b) 9 : 1

c) 3 : 17

d) 5 : 3

**Correct Answer (b) 9:1**

**Shortcut Solve**: 3/5 X 10 = 6; 2/5 X 10 = 4; 10+6 : 4 = 16 : 4 = 4:1; 4/5 X10 = 8; 1/5 X 10 = 2; 10 + 8 : 2 = 18 : 2 = 9: 1

8)
A merchant mixes three varieties of rice costing Rs.20/kg, Rs.24/kg and
Rs.30/kg and sells the mixture at a profit of 20% at Rs.30 / kg. How many kgs

a) 1
kg

b) 5 kgs

c) 3 kgs

d) 6 kgs

b) 5 kgs

c) 3 kgs

d) 6 kgs

**Correct Answers (b) 5 kg**

**Shortcut Solve:**20:5X24:2X30 = 20:120:60= 200; 200/8 = 25; 25 X 20% = 5; so 25 +5 = 30; Answers is 5

9)
How many kgs of Basmati rice costing Rs.42/kg should a shopkeeper mix with 25
kgs of ordinary rice costing Rs.24 per kg so that he makes a profit of 25% on

c) 16 kgs

d) 200 kgs

b) 12.5 kgs

c) 16 kgs

d) 200 kgs

**Correct Answer (a) 20 Kgs**

**Shortcut Solve**: 20X42: 25X24 = 840: 600 = 1440/45 = 32; 32X25% = 8; 32+8 = Rs 40; so with the answer (a) it gives correct figure.

10)
A zookeeper counted the heads of the animals in a zoo and found it to be 80.

b) 30

c) 60

d) 50

b) 30

c) 60

d) 50

**Correct Answer (d) 50**

**Shortcut Solve**: x+y = 80……..(i) ; 2x +4y = 260…….(ii); (i) X4= 4x +4y = 320; 2x = 60 ; x = 30; 30 +y = 80; y = 80 – 30 = 50
