2.I enjoy making curry. The recipe i like most uses 2 tablespoons of oil.There are 15ml in a tablespoon.From a full bottle I can make 8 curries but i find that i have 10ml of oil left over.How much oil is there in a full bottle?

Answer 1

`\textsf {See below :}`

Explanation:

`\textsf {Question 1}\\`

`\textsf {The only difference in a leap year is that February will have 29 days.}`

`\implies \textsf {Days in May, June, July = 31 + 30 + 31 = 92}`

`\implies \textsf {Days in January, February, March = 31 + 29 + 31 = 91}`

`\implies \textsf {Difference = 92 - 91 = 1}`

`\textsf {There is 1 more day in May, June, and July combined than}\\\textsf {in January, February, and March combined in a leap year.}}`

`\textsf {Question 2}`

`\textsf {Oil used in making 1 curry = 2(15) = 30 ml}`

`\textsf {Full bottle = 8 curries + 10 ml}`

`\textsf {Full bottle = 8(30) + 10}`

`\textsf {Full bottle = 240 + 10}`

`\textsf {Full bottle = 250 ml}`

Answer 2

1) one more day

2) 250 ml

Explanation:

in a leap year-

may = 31 days

june = 30 days

july = 31 days

(92 days)

january = 31 days

february = 29 days

march = 31

(91 days)

so, there is 1 more day.

------

to solve, I will write the value of 2 tablespoons as 30 ml (using the conversion rate provided)

so, 1 curry uses 30 ml.

If you have made 8 curries, you have used 240 (8 × 30 = 240) ml

If you have 10mls left over, that means the full bottle has

used + 10 mls

and we know that we have used 240, so in a full bottle,

there must be 250 (240 + 10) ml

250 ml

hope this helps!! :)
