Answer:
Mathematics book costs Rs. 2543=Rs. 4103
And Science book costs Rs. 2021=Rs. 241
To compare fractions we first make their denominators equal
For this we take the L.C.M of4 and 2 which is equal to 4
So, we multiply the numerator and denominator by 2 to get
⇒2×241×2=482
Clearly 4103 is greater is than 482
Hence, Mathematics book costs more than Science book by 4103−482=421=Rs. 5.25
Mathematics book
costs Rs. 2543-Rs. 4103
And Science book costs Rs. 2021 Rs. 241
For this we take
the L.C.M of4 and 2 which is equal to 4
→ 2×241x2=482
Hence, Mathematics book costs more than Science book by 4103-482=421=Rs. 5.25
