A glass when full of milk, weighs 1 kg. It weighs 0.75 kg when the glass is half full. What is weight of the empty glass?
Solution
Correct Answer: Option D
Glass এর ওজন = x কেজি
Milk এর ওজন = y কেজি
এখন
x + y = 1..................(1)
x + y/2 = 0.75
⇒ (2x + y)/2 = 0.75
⇒ 2x +y = 1.5..................(2)
(2) - (1)
⇒ 2x + y - (x + y) = 1.5 - 1
⇒ 2x + y - x - y = 0.5
⇒ x = 0.5
Glass এর ওজন = 0.5 কেজি
Milk এর ওজন = y কেজি
এখন
x + y = 1..................(1)
x + y/2 = 0.75
⇒ (2x + y)/2 = 0.75
⇒ 2x +y = 1.5..................(2)
(2) - (1)
⇒ 2x + y - (x + y) = 1.5 - 1
⇒ 2x + y - x - y = 0.5
⇒ x = 0.5
Glass এর ওজন = 0.5 কেজি
