1.	12. In a godown one-fifth of the acid is sulphuric and one-thirdhydrochloric; besides that is contains 15 dozen bottles of nitric and 30of carbolic: how much sulphuric and hydrochloric does it contain?
Answer» Let total bottles in godown be n Then,Bottles of sulphuric acid = n/5Bottles of hydrochloric acid = n/3Bottles of nitric acid = 512 = 60Bottles of carbolic = 30 As per given conditionn/5 + n/3 + 60 + 30 = nn - n/5 - n/3 = 90(15n - 3n - 5n) = 90157n = 1350n = 1350/7 = 192.85 Then quantity of sulphuric acid= n/5 = 192.85/5 = 38.57 Quantity of hydrochloric acid= n/3 = 192.85/3 = 64.2

Answer»

Let total bottles in godown be n

Then,Bottles of sulphuric acid = n/5Bottles of hydrochloric acid = n/3Bottles of nitric acid = 5*12 = 60Bottles of carbolic = 30

As per given conditionn/5 + n/3 + 60 + 30 = nn - n/5 - n/3 = 90(15n - 3n - 5n) = 90*157n = 1350n = 1350/7 = 192.85

Then quantity of sulphuric acid= n/5 = 192.85/5 = 38.57

Quantity of hydrochloric acid= n/3 = 192.85/3 = 64.2
