Using 1,500, 1,200, and 400, 1,000 cannot be formed as they can’t sum up precisely. Numbers like 14,000, 15,000, and 16,000 can be made using appropriate combinations. Some thousands, however, remain impossible.

class 6 Mathematics Textbook Chapter 3 question answer
With 1,500, 1,200, and 400 as options, 1,000 cannot be made, as these numbers don’t combine precisely. However, numbers like 14,000 can be formed (1,200 × 10 + 400), 15,000 (1,500 × 10), and 16,000 (1,200 × 12 + 400). Exploring other combinations reveals gaps: some thousands cannot be achieved due to limitations in available increments. This exercise highlights the constraints of arithmetic operations and the creative possibilities in making numbers.
