# In standard form 72 crore is written as

A. 72 × 10^{7}

B. 72 × 10^{8}

C. 7.2 × 10^{8}

D. 7.2 × 10^{7}

Answer :

Let us first understand the number of zeroes in a crore,

One lakh = 1, 00,000

Number of zeroes = 5

Ten Lakhs = 10, 00, 000

Number of zeroes = 6

One crore = 1, 00, 00, 000

Number of zeroes = 7

Ten crore = 10, 00, 00, 000

Number of zeroes = 8

Therefore 72 crore = 72, 00, 00, 000

Number of zeroes = 7

Number of terms to be shifted after decimal point = 8

72, 00, 00, 000 = 7.2 × 10^{8}

So the correct answer is C.
