Match the LIST-I with LIST-II | | LIST-I (Expression) | | LIST-II (Value) | |---|---|---|---| | A. | $(550\%\text{ of }250) \div 275$ | I. | 129.58 | | B. | $38\%\text{ of }341$ | II. | 231.6 | | C. | $15\%\text{ of }578+22.5\%\text{ of }644$ | III. | 156.8 | | D. | $140\%\text{ of }56+56\%\text{ of }140$ | IV. | 5 | Choose the correct answer from the options given below:
Solution
✅ Correct Option: 3
Work out each expression in LIST-I one by one. A. $(550\%\text{ of }250)\div275$ $=\dfrac{550}{100}\times250\div275$ $=1375\div275$ $=5$ B. $38\%\text{ of }341$ $=\dfrac{38}{100}\times341$ $=129.58$ C. $15\%\text{ of }578+22.5\%\text{ of }644$ $=86.7+144.9$ $=231.6$ D. $140\%\text{ of }56+56\%\text{ of }140$ Both halves are equal here, because $a\%$ of $b$ always equals $b\%$ of $a$. $=78.4+78.4$ $=156.8$ Time saver: once A gives 5, only the options starting with A-IV survive, and one more calculation (C) settles it.
