Rules
(i) (odd number) + (Composite odd number)
(ii) (Even number) + (Odd number)
(iii) (Even number) ? (Perfect square number), then (Perfect square number) - (Even number)
(iv) (Odd number) ÷ (Prime odd number)
(v) (Odd number) - (Even number)
1st Row 12 64 17 ? 64 - 12 = 52 [rule (iii)]
? 52 + 17 = 69 [rule (ii)]
= m
2nd Row 20 m 16 ? 20 69 16
? 20 + 69 = 89 [rule (ii)]
? 89 - 16 = 73 [rule (v)]
? Resultant of second row = 73
Yes, Every integer is a rational number. A rational number is a number which can be expressed as a ratio of two integers numerator and denominator where (the denominator not being 0 ).
Hence, Every integer can be expressed in ratio of two integers.
Fruits reduced by 1/4.
Total no. of bags N = 5
Formula to find no. of fruits in 1st bag = 4^n
Last Bag = 4 fruits.
That means, 4th bag = 4 x 4 = 16 fruits
3rd bag = 16 x 4 = 64 fruits
2nd bag = 64 x 4 = 256 fruits
1st bag = 256 x 4= 1024 fruits.
We all know about BODMAS rule, by using that
3x3x3+3+3/3
= 3x3x3+3+1
= 27+3+1
= 27 + 4
= 31
Hence, 3x3x3+3+3/3 = 31.
Number - '79246358' If the digits are arranged in descending order from left to right, new number = 98765432 Difference between the digits which are third from the right and second from the left = 8 - 4 = 4.
Perimeter = 36
? 2 ( l + w ) = 36
? l + w = 18
Since length and width are positive integers in centimeters.
Therefore, possible dimensions are :
( 1, 17 )cm , ( 2, 16 ) cm , ( 3, 15 ) cm, (4 , 14) cm, ( 5,13) cm, ( 6, 12) cm , ( 7, 11) cm, ( 8, 10 ) cm, ( 9, 9) cm.
Hence, there are 9 rectangles.
We know that, any decimal number when multiplied by the multiples of 10, the decimal point moves to right the number of zeroes in the multiplying number.
For example ::
0.0410 x 100 = 4.10 (Number of zeros in 100 are 2. So, the decimal point in 0.0410 moves two places to the right and becomes 4.10.)
Similarly, here in the option C) 5.008 x 10^3 kms it makes 5008 kms as the number of zeros in 10^3 i.e, 1000 are 3 and 5.008 becomes 5008.
