Question

Find The Result Of Subtracting The Sum Of All Integers Between 20 And 30 From The Sum Of All Integers From 20 To 30.

Plz Can Anyone Give Me Some Thanks

Answer 1

50

Step-by-step explanation:

Sum of the all integers from 20 and 30

20+21+22+23+24+25+26+27+28+29+30=275

Sum of the all integers between 20 and 30

21+22+23+24+25+26+27+28+29=225

∴ Required number= (Sum of the all integers from 20 and 30)-(Sum of the all integers between 20 and 30 )

=275-225

=50

Answer 2

Sum of integers from 20 to 30 = 275

sum of Integers Between 20 to 30 = 225

Difference = 275 - 225

= 50
