1.	The marked price of a tunic and jeans are in a ratio of 1 : 2. The shopkeeper gives a 40% discount on the tunic. If the total discount on both is 30%, the discount offered on the jeans is?1. 35%2. 30%3. 20%4. 25%
Answer» Correct Answer - Option 4 : 25% Given: Marked price of tunic and jeans = 1 : 2 Discount on tunic = 40% Total discount = 30% Concept used: S.P = M.P × (100 – D%)/100 Calculations: Let the Marked Price of tunic be x Let the Marked Price of jeans be 2x. Let the discount on jeans be y% According to the question ⇒ (60/100) × x + ((100 – y)/100) × 2x = (70/100) × (x + 2x) ⇒ (3x/5) + (100 – y)x/50 = 21x/10 ⇒ (100 – y)x/50 = 3x/2 ⇒ (100 – y) = 75 ⇒ y = 100 – 75 ⇒ y = 25% ∴ The discount on jeans is 25%.

Answer» Correct Answer - Option 4 : 25%

Given:

Marked price of tunic and jeans = 1 : 2

Discount on tunic = 40%

Total discount = 30%

Concept used:

S.P = M.P × (100 – D%)/100

Calculations:

Let the Marked Price of tunic be x

Let the Marked Price of jeans be 2x.

Let the discount on jeans be y%

According to the question

⇒ (60/100) × x + ((100 – y)/100) × 2x = (70/100) × (x + 2x)

⇒ (3x/5) + (100 – y)x/50 = 21x/10

⇒ (100 – y)x/50 = 3x/2

⇒ (100 – y) = 75

⇒ y = 100 – 75

⇒ y = 25%

∴ The discount on jeans is 25%.
