Answer: 1967
Step-by-step explanation:
Ada was 15 years when her sister Ngozi was 18 years.
This means that Ngozi is older than Ada by:
= 18 - 15
= 3 years
If Ngozi is older by 3 years, this means that she must have been born 3 years earlier than Ada
If Ada was born in 1970, Ngozi was born:
= 1970 - 3
= 1967

rs 30 per litre.
Step-by-step explanation:
We have 90 litres left after the leakage and we paid rs 2500 for it. To gain a 8% profit we have to sell 90 litres for 2500 * 1.08 = rs 2700.
So each litre has to be sold for rs 2700 / 90 = rs 30.
