Siri does 2/5 piece of work in 10 days.ankit does 5/9 of remaining work in 15 days and gaurav finishes remaining work in x days.if they can do whole work in 450/43 days working together find value of x

Answer 1

Answer:

Step-by-step explanation:

2/5=10 days

3/5=(3/5×5/2)=3/2×10=15 days

25 days

1/3=15

Hence 1= 3×15=45 days

1/3+2/5

=11/15

4/15=x

(1/25)×(450/43)+(1/45)×(450/43)+(1/y)×(450/43)=450/43

18/43+10/43+(450/43)(1/y)=450/43

422/43=(450/43)(1/y)

422/450=1/y

y=450/422

= 225/211=1

Hence 4/15=(4/15)×(225/211)

x = 60/211
