Question

Write a number between 100 and 200 which is
a) divisible by 5 but not by 10. (b) divisible by 3 its question answer

​

Answer 1

Answer:

a)10

similarly we can find the answer of

b)33

Step-by-step explanation:

Sol a) AP=105,115,125......195.

a=105

d=10

l=195

Now,

we have find n(the number between 100and 200)

we know that the formula for

l=a+(n-1)d. ...(1)

now we have to put value of a,d,l. in equation

195=105+(n-1)10

195=95-10n

100=10n

hence n = 10
