I am a 4-digit odd number. The digit in my tens place is the smallest odd number. The digit in my ones place is 4 more than the digit in the tens place. The digit in the thousands place is thrice the digit in the hundreds place. If the digit in the hundreds place is […]
John has $60 and Peter has $40 in each of their bank accounts. Every day, John deposits $5 while Peter deposits $9. In how many days will Peter have $40 more than John?———————————————————-One of the fundamental building blocks of heuristic problem sums is the concept of “Differences”.
