প্রশ্ন: A , B and C enter into partnership by making investments in the ratio 3:5:7 . after a year , C invests another tk.337600 while a withdraws tk. 45600, the ratio of investments then changes to 24:59:87 . How much does a invest initially ?

ব্যাখ্যা:

ধরি, A এর initial investment 3x

B এর inital investment 5x

C এর inital investment 7x

( 3x : 45600) : 5x = 24 : 59

3x - 45600/5x = 24/59

x - 15200 /5x = 8/59

59x - 40x = 15200 × 59

x = 15200 × 54 /19

x = 47,200

A এর initial investment ( 3 × 47200) = 1,41,600
