ramlal and pintu took a contract to white wash a house in 3 day. If they washed the 3/8 house first day and 3/7on the second day, what part of the house they white washed the third day
Answers
Answer : They will wash 11/56 part of the house on day-3
Step-by-step explanation:
1)The first step is to bring the fraction of the house on the first day and the fraction of house they washed on second day into like fractions.
2)To bring them to like fractions, we have to find their LCM.
3)The LCM of 8&7 is 56
4) Now you have to bring both the denominators to 56
5) Once you do that you will get 21/56 instead of 3/8 and 24/56 instead of 3/7
6) Now you have to add 21/56 and 24/56 i.e. day 1 and day 2
7)After you add them you will get 45/56
8)Now you have to subtract the sum of two days(45/56) from the total (i.e.56/56)
9) After you subtract you will get 11/56 which is day 3
