$$= 5000 - 1700 $$
Principal $$= 3300$$
Therefore, Sam invested Rs. $$3300$$.

A
$$0.45$$

B
$$0.0045$$

C
$$45.00$$

D
$$0.54$$

Solution

Converting a given fraction into decimal:

$$45\% =$$ $$\dfrac{45}{100}$$

Question 5
1 / -0

The cost price of $$20$$ articles is the same as the selling price of x articles. If the profit is $$25$$%, then the value of x is:

A
$$15$$

B
$$16$$

C
$$18$$

D
$$25$$

Solution

Let C.P. of each article be $$Re. 1$$ C.P. of x articles $$= Rs. x$$.
S.P. of x articles $$= Rs. 20$$.
$$Profit = Rs. (20 - x)$$.
$$\therefore \left (\dfrac {20 - x}{x}\times 100 = 25\right )$$
$$\Rightarrow 2000 - 100x = 25x$$
$$125x = 2000$$
$$\Rightarrow x = 16$$
Question 6

$$60\%$$ of what number if $$45$$?

A
$$27$$

B
$$30$$

C
$$60$$

D
$$75$$

E
$$90$$

Solution

Let the number be $$ x $$
So, $$ 60 $$ $$\%$$ of $$ x = 45 $$
$$ \Rightarrow \dfrac {60}{100} \times x = 45 $$
$$\Rightarrow 60 \times x=45 \times 100$$
$$ \Rightarrow x =75 $$
Question 8
