Q 18 Which of the following is the largest number?
Ops: A
420% of 65
220% of 122
C.
900% of 12
110% of 333​

Answer 1

Answer

In order to make 137, 182 and 422 completely divisible by the greatest number, we need to subtract 2 from each term, so

137-2 = 135, 182-2 = 180 and 422-2 = 420

Now HCF of 135, 180 and 420 is

135 = 3×3×3×5

180 = 2×2×3×3×5

420 = 2×2×3×5×7

Hence HCF of 135, 180 and 420 is 3×5 = 15

Hence the greatest number that will divide 137, 182 and 422 leaving the remainder 2 in each case is 15.

So the correct answer is 15.

Answer 2

Step-by-step explanation:

Multiply and get a number

• (420/100)×65= 273
• (220/100)×122= 268.4
• (900/100)×12= 108
• (110/100)×333= 366.3

Compare, so, 110%of 333 is the largest number.
