Hi Kamala, 0 is the value of K in this solution explanation. We have have assumed a variable K for framing the equation to get the number satisfying both conditions given in the question. K can range values from 0 to infinity. The condition given in the question is that the number finally obtained from this equation(involving k): -should satisfy the conditions in the question and -be a natural number. For K=0, our number turns out to be 53(satisfying both conditions in the question). Likewise for K=12, we get number as 977 which is the last number under 1000 (satisfying both conditions in the question). So totally '13 such numbers' is the required answer to this question.
thanks a lot, sir
Thanks Baskar!

How we get reminder 4 when we divide 4/7
Hi,
Dividend = Divisor × Quotient + Remainder
4 = 7 × 0 + 4
Hence, 4 will be the remainder when we divide 4 by 7.
Hello Sir, Why are we adding 0, as the question says natural numbers soo answer shld b 12.
