Question

A student got a 10% increase in his pocket money for

bearing Wifi expenses due to lockdown, If his new

increased pocket money is ₹1540, Find his original

one. ​

Answer 1

Answer:

₹1400

Step-by-step explanation:

let x be the orginal pocket money

10% increase in pocket money is ₹1540

x+10%x =1540

x+(10/100)x =1540

x+(1/10)x=1540

11x/10=1540

11x=15400

x=1400

therefore the original pocket money is ₹1400
