Answer:
He made 20 cups of coffee in total.
Step-by-step explanation:
No. of cups remained =3
% of coffee consumed = 85%
x - 85/100 × x = 3
x - 17x/20 = 3
20x/20 - 17x/20 = 3
3x/20 = 3
3x = 3 × 20
3x = 60
x = 60/3
x = 20
He made totally 20 cups of coffee
Check ⇒
20 - 85/100 × 20 = 3
20 - 85/10 × 2 = 3
20 - 85/5 = 3
20 - 17 = 3
3 = 3
L.H.S = R.H.S
Hence, verified
The answer is correct.
