Answer 1

Step-by-step explanation:

Dear Student,

Please find below the solution to the asked query:

We form frequency table from given information , As :

Daily expenditure ( In Rs. ) Frequency ( f )

210 - 215 3

215 - 220 5

220 - 225 2

225 - 230 3

230 - 235 2

235 - 240 4

240 - 245 3

245 - 250 2
