(1000 – 250) = 750 টাকা।
2 দিনে জমা হয় = (250 – 200) টাকা।
= 50 টাকা।
50 টাকা জমাতে লাগে 2 দিন।
750 টাকা জমাতে লাগে = (2 × 750 ÷ 50) দিন।
= 30 দিন।
সুতরাং,
(750+250) = 1000 টাকা জমাতে লাগবে (30+1) দিন।
= 31 দিন।
Initially savings (250-200) = 50 taka
thus, for 1000 taka saving he spend (1000/50) = 20 times,
That means 40 days
