Question

I have 60 ten-rupee notes in my hand. The numbers on those notes are in order. If the number on the first note is 7575, what will be the number on the last note?

• A. 7637
• B. 7636
• C. 7635
• D. 7634

Answer 1

Answer:

D. 7634

If the number on first note is 7575 then number on 60th note will be

tn = a + (n-1) d

• a = 7575

• n = 60

• d = 1

t₆₀ = 7575 + (60-1) x 1

t₆₀ = 7575 + 59

t₆₀ = 7634
