Question
A man invested a sum of Rs. 25,000. He invested some
part at 5% p.a. and remaining at 5.5% p.a. How much money did he invest at 5% p.a.? Statement I : The total interest amount paid after 1 year was Rs. 2230. Statement II : The interest on one sum was twice that on the other. In each of the following questions, a question and some statements are given. You have to decide whether the data given in the statements are sufficient to answer the question or not.Solution
Let first part is Rs x , then remaining is Rs (25000 - x) From statement I ((x * 5 * 1)/100) + ((25000 - x) * 5.5 * 1/100) = 2230 So, "x" can be calculated. From statement II , ((x * 5 * 1)/100) = 2 * ((25000 - x) * 5.5 * 1/100) So, "x" can be calculated.
(√ 121 x 41) + (3√343 x √289 ) = ? x 19  Â

737 + 149 - ?²- 367 = 14 X 25(√ 1444 ÷ 5) × 3.25 = ?
522 + 160% of 80 - 130 = ? X 13Â
54% of 250 = 6 × 21 + √?
300% of (3341 – 471) = ? × (√4225/195)
