the correct answer is B. there are two small semicircles that form one circle when joined. so after joining it forms 1 circle with a diameter of 14 which means it has a radius of 7. area= 7*7*(22/7)= 154 in the big semicircle it has a diameter of 28 which means it has a radius of 14. area = (14*14*22)/(7*2) = 616 area of shaded part = 616-154= 462 thus the correct option is B

divide 2304 by 4. the quotient so obtained is 576. Now, divide 576 by 6... we get the quotient as 96. So, any no. greater than 96 is the answer... in this case it is 106.

Answer is B 2* 3 = 24 2 * Y = 24 So Y= 3 Y= X- 1 So x-1 = 3 X = 4 X + Y = 7

OPTION: B 7 3x4 =12 . 24 IS DIVISIBLE BY 12 SO X=4 Y= X-1 = 4-1=3 2X3=6. 24 IS DIVISIBLE BY 6 SO X+Y = 4+3=7

The correct answer provided for given problem is 6 not 7. But how they have calculated it is not clear. If you take sum of two consecutive numbers it should be an odd number. So 6 also doent seem to be a correct answer.
