Question

If the price of tea increased by 7.69 them by how many % should a person reduce the consumption of tea so that there no impact on his expenditure​

Answer 1

Now we know that by expanding the numbers we can write as

➠ 167 = 1 x 100 + 6 x 10 + 7

➠ 716 = 7 x 100 + 1 x 10 + 6

➠ 671 = 6 x 100 + 7 x 10 + 1

Now,

⟾ 167 + 716 + 671  

⟾ 1 x 100 + 6 x 10 + 7 + 7 x 100 + 1 x 10 + 6 + 6 x 100 + 7 x 10 + 1

⟾  (1 + 7 + 6)100 + (6 + 1 + 7)10 + (7 + 6 + 1) 14 x 100 + 14 x 10 + 14

⟾ 14(100 + 10 + 1)

⟾  14 x 111

⟾  14 x 3 x 37 (3 x 37 = 111)

⟾ 42 x 37

So quotient is 42 when 1554 is divided by 37.

Similarly for 111 we get

⟾  14 x 1 x 111

⟾  14 x 111  

So quotient is 14 when 1554 is divided by 111
