the cost of 1 notebook is 43 rupees
3)tina is 7 year 5 month year old

Answer:
1. ans= 555 min
2. ans= RS43
3. ans= 89months
4. ans= 69750ml
5. ans= 28 days
6. ans = 142 hours
Step-by-step explanation:
1. = We know that 1 hour has 60 minutes so 9 hour has? = 9x60 = 540 min + 15 min = 555 min.
2. If 6 notebooks cost Rs 258 then 1 notebook cost? = 258/6 = Rs43
3. We know that a year has 1 month so 7 years has? = 12x7= 84 + 5 months = 84+5 = 89 months.
4. 71250-1500 = 69750ml.
5. We know that a week has 7 days. So in 4 weeks how many days are there? = 7x4= 28 days.
6. We know that a day has 24 hours so how many hours are there in 6 days? = 24x6=142 hours.
