ATQ,
Since, simple interest = {(sum invested X time X rate)/100} where sum
invested is in Rs., time in years and rate in percentage per annum
Interest received by Ravi = {(3200 X 10 X 5)/100} = Rs. 1600
Interest received by Sunil = {(4000 X 9 X 4)/100} = Rs. 1440
Required difference = 1600 - 1440 = Rs. 160

(15.99)2 + 219.98% of 20.01 = ?2 × 75.01%
35.11% of 159.99 + √195.97 ÷ 7.02 = ?
?% of (95.31 ÷ 18.97 × 70.011) = 174.98
