Consider the following assumption and two statements: Assumption : A number ‘ABCDE’ is divisible by 11.
Statement IE-D+C-B+A is divisible by 11.
Statement IIE-D+C-B+A = 0.
Which one of the following is correct ?
Elementary MathematicsNumber System
- AOnly statement -I can be drawn from the assumption
- BOnly statement -II can be drawn from the assumption
- CBoth the statements can be drawn from the assumption
- DNeither of the statements can be drawn from the assumption
Explanation
Divisibility by 11 depends on the alternating sum E-D+C-B+A; only statement I follows.
