Question

9. A farmer has 1500 mango saplings. He wants to plant these in such a way that the number of rows
and the number of columns remain same. Find the minimum number of plants he needs more for
the same
10. There are 600 students in a school. For the morning assembly they have to stand in such a manner
that the number of rows is equal to the number of columns. How many students would be left out
in this arrangement?​

Answer 1

Answer:

Step-by-step explanation:

9. If by the question you mean that the first row has 6 trees, then 12, then 18 and so on. ... This is a problem is AP, where the sum is 720 and d= 6. ... If he plants them in rows of 37 in each, he will have 8 trees left, and if he plants in rows of 43 trees

10.there are 600 children in a school for PT drill they have to stand in such a way that number of rows is equal to the number of column

we have to find that how many children should be left in this arrangement

so according to the question the number which should be subtracted from 600 to make it a perfect square has to be calculated

the square root of 600 can be calculated by long division method

2| 600| 24

-4

44|200 |

-176

24

so the reminder is 24

the square of 24 is less than 600

therefore if we subtract 24 from 600 and we get 600 - 24 = 576..

Is that your answer...
