Answer 1

Answer:

option B is correct I am sure explanation I will give you

Step-by-step explanation:

first we try First One 79 × 250 = 19,750

next 80 - 79 = 1

next 1 × 750 = 750

19,750

+

750 = 20500 so it is wrong because Rs 25500 is the total cost but here it is 20500 so It is wrong

second one 69 ×250 = 17,250

next 80 - 69 = 11

next 11 × 750 = 8250

17,250 + 8250 = 25500 it is the correct rupees of the given cost so it is the correct one ok I think it is helpful to you

third one 60 × 250 = 1500

next 80 - 60 = 20

next 20 × 750 = 15000

15000 + 15000 = 30000

so it is wrong because 25500 is the total cost but here it is 30000 so it is wrong

fourth one and the last one 59 × 250 = 14750

next 80 - 59 = 21

next 21 × 750 = 15,750

14750 + 15,750 = 30,500 it is wrong because 25500 is the total cost but here it is 30500 so it is wrong
