Question 44

After interchanging which two numbers will the value of the given expression be ‘173’?

$$52 - 36 + 141 \times 63 \div 47$$

Solution

$$52\ -\ 36\ +\ 141\times\ 63\ \frac{\ 47}{ }=173$$

141 and 52

$$141-36\ +\ 52\times\ 63\ \frac{\ 47}{ }=173$$

$$105\ +\ 52\times\ 63\ \frac{\ 47}{ }=173$$

$$105\ +\ 3276\ \frac{\ 47}{ }=173$$

$$105\ +\ 69.70=173$$

$$174.7=173$$

47 and 63

$$52\ -\ 36\ +\ 141\times\ 47\ \frac{\ 63}{ }=173$$

$$16\ +\ 141\times\ 47\ \frac{\ 63}{ }=173$$

$$157\times\ 47\ \frac{\ 63}{ }=173$$

$$7379\ \frac{\ 63}{ }=173$$

$$117.12=173$$

52 and 36

$$36\ -\ 52\ +\ 141\times\ 63\ \frac{\ 47}{ }=173$$

$$\ -\ 16\ +\ 141\times\ 63\ \frac{\ 47}{ }=173$$

$$\ -\ 16\ +\ 8883\ \frac{\ 47}{ }=173$$

$$\ -\ 16\ +189=173$$

$$173=173$$

63 and 141

$$52-36\ +\ 63\times\ 141\ \frac{\ 47}{ }=173$$

$$16\ +\ 63\times\ 141\ \frac{\ 47}{ }=173$$

$$16\ +\ 63\times\ 3=173$$

$$16\ +\ 189=173$$

$$205=173$$

Hence option C is the correct answer L.H.S=R.H.S
