What will come in place of the question mark (?) in the given questions ?
Solution
Expression : $$(\frac{1\frac{7}{60}}{1\frac{27}{40}})\times(1\frac{29}{34})\times? = 231$$
=> $$\frac{\frac{67}{60}}{\frac{67}{40}} \times (\frac{63}{34}) \times x = 231$$
=> $$\frac{40}{60} \times (\frac{63}{34}) \times x = 231$$
=> $$\frac{2}{3} \times (\frac{63}{34}) \times x = 231$$
=> $$\frac{21}{17} \times x = 231$$
=> $$x = 231 \times \frac{17}{21}$$
=> $$x = 11 \times 17 = 187$$
