of the day?​

Answer 1

Answer:

Step-by-step explanation:

Let the money devanshi had in the beginning be = x

She gave 240 to her brother , so money left now =x -240

She later buys a book for herself now money remaining is = (x-240)-80

Later she adds 300 so money in her purse becomes = 450

(X)-240-80+300=450

X-320+300=450

X-20=450

X=450+20

X=470

She had 470 rs in her purse at the starting

Answer 2

Answer:

470 is the correct answer.

Given:

• Devyanshi has some money in her money box.
• She gives 240 to her brother and buys a book for 80 for herself.
• She later puts 300 into the box.
• At the end of the day she finds she has 450 in the money box

To find:

How much did she have in it at the start of the day

Solution:

let the money that Devyanshi initially had be y.

according to the question,

450 = y -240 - 80 + 300

450 = y - 320 + 300

450 = y - 20

y = 450 + 20

y = 470

Hence, 470 is the correct answer.
