b) face value = 5 and place value = lakh

999999999

Let's divide this number by 15

=> the remainder is equal to 9

Show the number perfectly divisible by 15 will be 999999999 - 9 as it is the remainder

Therefore the greatest 9 digit number which perfectly divisible by 15 is 999999990

iv)

Total number of pages

The last two digits make the number 16 and 16 is nearer to 20 than it is to 10.

So the estimated value of 17301816 is 17301820.

v)

(52+[-21])-(-25+38)

52-21+25-38
