Question
Monthly incomes of Anil and Sunil are Rs. 36,000 and Rs.
_______, respectively. Anil and Sunil save 22% and 28% of their respective incomes. The difference between their savings is Rs. _______. The values given in which of the following options will fill the blanks in the same order to make the above statement true: I. 38000, 2280 II. 32000, 1080 III. 40000, 3600 IV. 35000, 1880Solution
ATQ, For I: Saving of Anil = 0.22 × 36000 = Rs. 7920 Saving of Sunil = 0.28 × 38000 = Rs. 10640 Required difference = 10640 – 7920 = Rs. 2720 (Not true) For II: Saving of Anil = 0.22 × 36000 = Rs. 7920 Saving of Sunil = 0.28 × 32000 = Rs. 8960 Required difference = 8960 – 7920 = Rs. 1040 (Not true) For III: Saving of Anil = 0.22 × 36000 = Rs. 7920 Saving of Sunil = 0.28 × 40000 = Rs. 11200 Required difference = 11200 – 7920 = Rs. 3280 (Not true) For IV: Saving of Anil = 0.22 × 36000 = Rs. 7920 Saving of Sunil = 0.28 × 35000 = Rs. 9800 Required difference = 9800 – 7920 = Rs. 1880 (True) So, IV is true.
