Step-by-step explanation:
Let B join after x months.
∴21000×12=36000×(12−x)
⇒252000=36000×12−36000x
⇒36000x=432000−252000
⇒36000x=180000
⇒36x=180
⇒x=
35
180
=5
Hence B joined after 5 months.
Answer:
Prakash joined after 5 months
Step-by-step explanation:
Given that Ravi started business with ₹2,10,000
after few months Prakash joined with ₹3,60,000
end of the year they got a profit ₹1,20,000 on each
the profit ratio will be 1 : 1
from above data Ravi invested in entire year
number of months Ravi invested = 12 months
let Prakash joined after x months
number of months Prakash invested = (12 -x) months
the ratio of the profit = 2,10,000 ×12 : 3,60,000 × (12 - x)
= 21× 12 : 36 × (12 -x)
= 21 : 3 (12-x)
= 7 : (12 -x)
we know that profit ratio = 1 : 1 = 7 : (12 -x)
⇒ =
⇒ 7 =12 -x
⇒ x = 12- 7
⇒ x = 5 months
