Answer:

Correction: It is 1835 in most questions as mentioned in grade 6 NSTSE 2009 which is given with options - a) 2035 b)  2060  c) 2075  d) 2080

Step-by-step explanation:

Now main formula is - 1835 + 60, 1835 + 120, 1835 + 180 ........

The number which 60 is multiplied can be replaced by 'n'.

So, formula becomes 1835 + 60n.

⚠️If the 'n' found in option is not an integer, then it is not the correct answer⚠️

Let's try this in the options

OPTION A

1835 + 60n = 2035

60n = 2035 - 1835

60n = 200

n = 200÷6

n = 33.3  ⚠️NOT INTEGER ⚠️

OPTION B

1835 + 60n = 2060

60n = 2060 - 1835

60n = 225

n = 225/60

n = 3.75 ⚠️NOT INTEGER ⚠️

OPTION C

1835 + 60n = 2075

60n = 240

n = 240/60

n = 4

OPTION D

1835 + 60n = 2080

60n = 2080 - 1835

60n = 245

n = 245/60

n = 4.083333 ⚠️NOT INTEGER ⚠️

CONCLUSION

option C is the only one that got 'n' as an integer, so, OPTION C - 2075 is the right answer
