1040 ko 130 pakad kyun liya?1050 bhi ho skta tha?

Question:

What approximate value should come in place of question mark (?)? (Note: You are not expected to calculate the exact value.)


623898 × 99 =? × 60,000

Options:
A) 1000
B) 1040
C) 1050
D) 1065
E) 1010
Solution:

623898 × 99 = ? × 60,000

Taking approximate values, 

⇒ 623900 × 100 ≈ ? × 60000

⇒ ? ≈ \(\frac{623900\times100}{60000}\)  ≈ 1039.8 ≈ 1040
