a 5% profit?

(a) 23%

(b) 150%

(c) 200%

(d) 180%

(e) None of
these.

**Answers with explanation**

1.(a) Total
increase = 8 * 2 = 16 years

So, total
age of two women = 35 + 45 +16= 96

Average age
of two women=96/2=48 years

2.(c) 2, 4,
6, ………… 100

Average =
(1st No. + Last No.) /2 = (2+100)/2 = 51

3. (a) S.I.
for 3 years = Rs. (12005 - 9800) = Rs. 2205.

S.I. for 5
years= Rs. 3675

Principal =
Rs. (9800 - 3675) = Rs. 6125

Hence Rate
= {(100 × 3675) / 6125 × 5} % = 12 %

4. a) Let
C.P. be Rs. x and S.P. be Rs. y.

Then, 3(y -
x) = (2y - x) y = 2x.

Profit =
Rs. (y - x) = Rs. (2x - x) = Rs. x.

So profit %
=100%

5. (D):

Short
tricks : Let the initial investment money ratio of Jon and Harry is 2x and 3x
So Jon , Harry and Ron ratio of investment is ( Jon : Harry : Ron )

= (2x X 12
) : ( 3x X 12 ) : ( 3x X 6 ) = 24 : 36 : 18 = 4 : 6 : 3

6. (B):

Suppose Ramesh invested Rs. x. Then,

Manoj : Ramesh = 120000 * 6 : x *12.

720000/12x: 6000/3000

x = 30000

7. (c) Let speed of cyclist = x kmph

480/(72 - x) X 5/18 = 32

x = 18 kmph

8. (a) Let
speed of 1st train = x kmph

(180 + 120)/(x X 5/18) = 20

x = 54 kmph

9.Let the number to be added x , Then

3 + x / 5 + x = 5 / 6

6 ( 3 + x ) = 5 ( 5 + x )

x = ( 25 – 18 ) = 7

So , the number to be added is 7 .

3 + x / 5 + x = 5 / 6

6 ( 3 + x ) = 5 ( 5 + x )

x = ( 25 – 18 ) = 7

So , the number to be added is 7 .

10. Profit=
5% (If case )

5% of CP
------> Rs. 27 So, CP = Rs. 540

Now, Loss%
= 10

Loss =Rs.
54 Required % = 54*100/27 = 200%
