Question:

Price of tea increased by 32%, expenditure increases by 10% only, initially consumption of tea was  10 Kg.  Find the current consumption. 

Options:

8

8\(\frac{1}{3}\)

6

6\(\frac{2}{3}\)

Correct Answer:

8\(\frac{1}{3}\)

Explanation:

                        Previous                       Current

Expenditure =      10                :              11                (10% = \(\frac{1}{10}\))

Price             =      25                :              33               ( 32% = \(\frac{8}{25}\))

Consumption =     \(\frac{10}{25}\)               :              \(\frac{11}{33}\)

                              \(\frac{2}{5}\)                 :              \(\frac{1}{3}\)

                               6                :             5

⇒ 6R = 10 kg (given)

⇒ 5R = 5 × \(\frac{10}{6}\) kg = 8\(\frac{1}{3}\) Kg

Hence, Current consumption = 8\(\frac{1}{3}\) kg

 

**Consumption = \(\frac{Exp.}{Price}\)
