1. The problem gives a ratio of 3:7 and a total amount of 210000. 2. We need to find the value corresponding to the first part of the ratio (3 parts). 3. The total parts in the ratio are $3 + 7 = 10$. 4. The value of one part is calculated by dividing the total amount by the total parts: $$\frac{210000}{10} = 21000$$ 5. The value corresponding to 3 parts is: $$3 \times 21000 = 63000$$ 6. However, 63000 is not among the options, so let's check if the question asks for the other part (7 parts): $$7 \times 21000 = 147000$$ 7. 147000 is also not an option, so let's verify if the ratio is used differently. 8. If the question asks for the difference between the two parts: $$210000 - 3 \times 21000 = 210000 - 63000 = 147000$$ 9. Since none of these match the options, let's check if the ratio is applied to find the smaller amount from the total. 10. The options closest to the parts are 90000, 190000, 120000, 130000. 11. Let's try to find the value of 3 parts as a fraction of total: $$\frac{3}{10} \times 210000 = 63000$$ 12. Let's try 90,000 as the value for 3 parts and check the ratio: $$\frac{90000}{210000} = \frac{3}{7}$$? 13. Simplify $\frac{90000}{210000} = \frac{9}{21} = \frac{3}{7}$, which matches the ratio. 14. Therefore, the value corresponding to 3 parts is 90000. Final answer: 90000
