Explanation

C.P. of 1 toy = 375/12 = Rs. 31.25

S.P of 1 toy = Rs. 33

Profit = 1.75/31.25 * 100 = 28/5 = 5.6%

Explanation

Given:

Selling Price (SP) = Rs. 49755

Profit Percentage = 7%

Let Cost Price (CP) be x.

SP = CP + Profit

49755 = x + 7% of x

49755 = x + 0.07x

49755 = 1.07x

x = 49755/1.07

x = 46500

Explanation

Let's say the cost price (CP) of the washing machine is x.

Given that the GST rate is 17%, the selling price (SP) would be:

SP = x + 0.17x

SP = 1.17x

Given that SP = Rs 15,912:

1.17x = 15912

x = 15912 / 1.17

x = 13600

Explanation

Total income = Mujahid's income + Wife's income

= 56,835 + 35,600 = 92,435

Expenditure = Rs 65,000

Savings = Income − Expenditure

= 92,435 − 65,000 = 27,435

Explanation

Let cost price = x
Loss of 20% means:
540,000 = x × 0.80 → x = 540,000 ÷ 0.80 = 675,000
To gain 7.5%:
New selling price = 675,000 × 1.075 = Rs. 725,625

(But this seems inconsistent with the options — let’s double-check)

Correction:
540,000 is after a 20% loss, so:
Cost Price = 540,000 ÷ 0.80 = 675,000

Now for 7.5% profit, Selling Price = 675,000 × 1.075 = Rs. 725,625

Explanation

Total parts = 2 + 3 + 7 = 12

Each part = 129,000 ÷ 12 = 10,750

Largest share = 10,750 × 7 =  75,250

Explanation

Profit=2/100×300=6

Explanation

Given:

- Cost Price (CP) = 100  

- Profit 

Formula:

- Selling Price (SP) = CP × (1 + profit/100)

Steps:

1. Profit amount = (2/100) × 100 = 2  

2. Selling Price = CP + Profit = 100 + 2 = 102  

Explanation

We are given two equations:

Let:

• Cost of one apple = x

• Cost of one orange = y

From the problem:

1. $4x + 2y = 30$
   

2. $$x+3y=15

   
   Step 1: Solve the system of equations

Equation (1):
$4x + 2y = 30$
Divide the whole equation by 2:
→ $2x + y = 15$→ (3)

Equation (2):
$x + 3y = 15$ → (2)

Step 2: Solve equations (2) and (3)

From (3):
$y = 15 - 2x$ → (4)

Substitute (4) into (2):
$x + 3(15 - 2x) = 15$
$x + 45 - 6x = 15$
$-5x+45=15$
$-5x=15-45=-30$
$$x=−30−5=6

Explanation

Given:

• 10 lb of meat at Rs 1.69 per lb

• 20 lemons at Rs 60 per dozen

Step 1: Cost of meat

$$10 text{ lb} times 1.69 = 16.90$$

Step 2: Cost of lemons

• 1 dozen = 12 lemons

• So, price per lemon = $frac{60}{12} = 5$ Rs per lemon

• 20 lemons =$20\times 5=100$ Rs

  Step 3: Total cost

$$16.90 + 100 = 116.90$$

 Correct answer: (D) None of these
