Question

India = 1,620. Philippines = 3,833. Indonesia = 2,410. Vietnam = 2,520. Japan = 17,802. South Korea = 17,531. China = 5,731. Hong Kong = 22,433. Singapore = 20,044. Choices are: a. Japan, b. South Korea, c. China, d. Hong Kong, e. Singapore

Answer 1

Combined income=1620+3833+2410+2520=10383. 92% of this is 9552 approx. So 10383+9552=19935. The nearest country with this income is Singapore (answer e), (but Hong Kong is higher again).
