Question

which is the 25 th number divisible by 9 anf 15 after 1000. solve step by step

Answer 1

1000/9 which gives 1 as remainder

so, 1000 + 8 = 1008

so, 1008/9 which gives 0 as remainder

9*25 = 225

1008+225 = 1233

after 1000, 1233 is 25 th number which is divisible by 9 after 1000

1000/15 which gives 10 as remainder

so, 1000 + 5 = 1005

so, 1005/15 which gives 0 as remainder

15*25 = 375

so, 1005 + 375 = 1380 is the 25 th number which is divisible by 15 after 1000
