মনেকরি,starting payment = x টাকা ∴ ২য় দিনে (x + 10) টাকা ৩য় দিনে (x + 20) টাকা ৪র্থ দিনে (x + 30) টাকা ৫ম দিনে (x + 40) টাকা ৬ষ্ঠ দিনে (x + 50) টাকা ৭ম দিনে (x + 60) টাকা প্রশ্নমতে, x + (x + 10) + (x+20) + (x + 30) = (x+40) + (x + 50) + (x + 60) ⇒ 4x + 60 = 3x + 150 ⇒ 4x - 3x = 150-60 ⇒ x = 90 ∴ starting payment ছিল 90 টাকাRelated questions
