• C. Orange juice worth ₹ 8
• D. All the three worth ₹ 12.5 (125 grams each)

Answer 1

The correct option is B

Litchi juice worth ₹ 16

Litchi juice worth ₹ 16

On calculating, the maximum amount of vitamins as per the quantity will be given by Litchi juice worth ₹ 16 only.

Quantity of litchi juice for ₹16= $\frac{250}{7}\times$ 16 = 571.43 gm

Vitamin content = 12 % of 571.43 = 68.57 gm

Quantity of pineapple juice for ₹ 15= $\frac{250}{10}\times$ 15 = 375 gm

Vitamin content = 15 % of 375 = 56.25 gm

Quantity of orange juice for ₹ 8= 250 gm

Vitamin content= 20% of 250 = 50gm

Quantity of mix juice = 125+125+125= 375 gm

Vitamin content = 20 % of 125 + 15 % of 125 + 12% of 125

= 47% of 125

= $\frac{47}{100}\times$125

= 58.75gm

Thus the highest vitamin content is in litchi worth ₹ 16.
