Question

in 2 days 20 hours a watch gains 20 seconds find how much time the watch will take to gain 35 seconds

Answer 1

→ Chapter : Ratio ←
≡ We know that:
⇔ 2 days 20 hours = 68 hours → Gain 20 seconds
⇔ N → Gain 35 seconds

≡ Solution:
⇒ $\frac{68}{N}=\frac{20}{35}$
⇒ $N=\frac{(68).(35)}{20}$
⇒ $N=\boxed{119}Hours=\boxed{4}Days\boxed{23}Hours$
