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 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.
