Answer 1

Answer:

Percentage of increases amount = 15

Increased cost = rs.1620

increased amount = 15% of 1620

= (15/100) * 1620

= 243

• Answer: Rs.243

Answer 2

Answer:

b) 212

Step-by-step explanation:

Let x be the price of Article and v know that 15% of x = 1620

So, 1620 = x + x × $\frac{15}{100}$

Now to add both values we have to take their LCM (Lowest Common Factor) . So here we will take 100 as the LCM

Now, 1620 = $\frac{100x + 15x}{100}$

1620 = $\frac{115x}{100}$

By Using Transposing Method ,

1620 × 100 = 115x

x = $\frac{162000}{115}$

X = Rs 1408

INCREASE PRICE = 1620 - 1408 = Rs. 212
