I have been asked this question by my college director while I was bunking the class.
The above asked question is from Age/Money/Denomination of Currency Word Problems topic in section Linear Equations in One Variable of Mathematics – Class 8
Right option is B. 23 rupees
For explanation: Let the amount received by the girl from the shopkeeper be x rupees.
∴ 27+x=50
∴ x=50-27
∴ x=23.
