Squaring

Find square of 43
= (43+3) * (43-3) + (3*3)
=(46*40) + 9
= (460*4) + 9
= 1840 + 9 = 1849

Multiplication

Multiply 62 with 32








Square root

Find square √ 1936
√ 1936 = √ 4 * √ 484 = √ 4 * √ 4 * √ 121 = 2*2*11 = 44

Time and Work

For example - A takes 10 days to complete a job. B takes 20 days to complete the same job. In how many days they will complete the job if they work together ?
A's efficiency = 100/10 = 10% per day
B's efficiency = 100/20 = 5% per days
A and B can do 15% of the work in a day if they work together. So they can do the whole job in 100/15 = 6.66 days or 6 days and 18 hours.
