A supply of juice lasts for 35 days, if its use is increased by 40%, then what would be the number of days less for the same amount of juice ?
Answer & explanation
Correct answer: option 4
Days × Consumption = Total Quantity of juice
*(if quantity of juice is constant then relation b/w Days and consumption is inverse)
40% = \(\frac{2}{5}\)
Earlier : Later
Consumption: 5 : 7
Days: 7 : 5
×5 ⇓
⇓ ×5
35 (given) ⇓
25 days
days less = 35 - 25 = 10
