Question 1
1 / -0

Opposite of profit of $$Rs.250$$ is

A
$$profit \ of \ Rs.50$$

B
loss of $$Rs.250$$

C
$$loss \ of \ Rs.150$$

D
none

Solution

$$\therefore $$Option B is correct.
Question 2
1 / -0

If the amount repaid is Rs. $$450$$ and the principal is Rs. $$415$$, then interest is equal to

A
Rs. $$25$$

B
Rs. $$35$$

C
Rs.$$ 45$$

D
Rs. $$50$$

Solution

Amount (A) $$= Rs. 450$$
Principal (P) $$= Rs. 415$$
$$A=I+P$$
$$I = A - P = 450 - 415 = Rs. 35$$
Question 3
1 / -0

To make a cup of tea, the ratio of water to milk is $$3: 1$$. To make $$4$$ cups of tea the ratio of water to milk is :

A
$$4 : 3 $$

B
$$12 : 1$$

C
$$12 :4$$

D
$$4 : 12$$

Solution

A $$cup$$ of tea has Water to Milk Ratio
$$W:M= 3:1$$
where $$W$$ and $$ M$$ are $$Water$$ and $$Milk$$
Now, $$4 $$ cups will have $$4 $$ times the $$Water$$ and $$milk$$ of a single $$cup $$.
So, the ratio will be
$$=\dfrac{3\times 4}{1\times 4}$$

$$=\dfrac{12}{4}$$ or $$12:4$$.
Question 4
1 / -0

The Simplest form of 144:28 is

A
$$\dfrac{28}{4}$$

B
$$\dfrac{36}{7}$$

C
$$\dfrac{7}{36}$$

D
$$\dfrac{1}{2}$$

Solution

The given ratio is $$144:28$$
divide the ratio by $$4$$ to simpify ratio$$=\dfrac{\dfrac{144}{4}}{\dfrac{28}{4}}=36:7$$
Question 5
1 / -0

How much should money lender lend at the simple rate of interest of $$15\%$$ in order to have $$\text{Rs. }3234$$ at the end of $$1\frac{1}{2}$$ years?

A
$$\text{Rs. }1640$$

B
$$\text{Rs. } 2620$$

C
$$\text{Rs. }2610$$

D
$$\text{Rs. } 2640$$
Question 6
1 / -0

A shopkeeper prefers to sell his goods at the cost price but uses a weight of 800 gm instead of 1 kg weight. He earns of profit of

A
2%

B
8%

C
20%

D
25%

Solution

Let CP of $$1 gm =Re1$$
Given : he sells $$800 gm$$ instead of $$1000 gm(1 kg)$$
So, CP of $$800gm=800Rs$$.
SP of $$800gm$$= CP of $$1000gm=1000Rs.$$
Profit=$$1000−800=Rs.200$$
Profit %=$$ \dfrac {200}{800}×100=25$$
Question 7
1 / -0

$$138\%$$ is equal to:

A
$$\displaystyle \frac{68}{50}$$

B
$$\displaystyle \frac{69}{50}$$

C
$$13.8$$

D
$$1.83$$

Solution

Given, $$138 \%=.....$$
We can write it as,
$$138 \% =\displaystyle \frac{138}{100} = \frac{69}{50}$$ .... On dividing by $$2$$
Question 8
1 / -0

The percentage of unshaded portion in the following figure is ____

A
$$25\%$$

B
$$50\%$$

C
$$75\%$$

D
$$100\%$$

Solution

$$\left(\dfrac {3}{4}\right)^{th}$$ of the portion is shaded in the given figure.

Therefore, percentage of unshaded portion $$=$$ $$\dfrac{3}{4}\times 100$$
$$= 75 \%$$
Question 9
1 / -0

$$\dfrac{3}{4}$$ means

A
75

B
75%

C
$$\dfrac{400}{3}$$

D
$$\dfrac{400}{3}$$%

Solution

$$\frac{3}{4} = \frac{3}{4} \times 100$$ % = $$75$$%
Question 10
1 / -0

Hari bought a pen for Rs. 125 and sold it for Rs. 120. The loss is

A
Rs. $$245$$

B
Rs. $$5$$

C
Rs. $$15$$

D
none

Solution

$$\Rightarrow$$ Cost price of pen is $$Rs.125$$
$$\Rightarrow$$ Selling price of pen is $$Rs.120$$
$$\Rightarrow$$ $$Loss=Cost\, price-selling\, price$$
$$\Rightarrow$$ $$Loss=125-120=Rs.5$$
