Step 1: Watch the video prepared by MockBank’s expert.

Step 2: Read the concepts that follow.

Step 3: Put a timer before you solve the previous year questions on decimal and fraction in quiz and record how much time it takes you to solve it.

Step 4: Send us questions in comments section below which took maximum time and we will tell you a faster way to solve it.

If X can do a piece of work in n days, work done by X in 1 day =1/n
If X does 1/n work in a day. X can finish the work in n days.
If X is thrice as good as Y in work,then

• Ratio of work done by X and Y= 3: 1
• Ratio of time taken to finish a work by X and Y = 1 : 3
