LET ME ANSWER FOR Q. 1)  The given number should be divisible by both 9 & 4 Thus, as per the rule , I] DIVISIBILITY TEST FOR 4  A number is divisible by 4 when the number formed by the last two rigjht hand digits is divisible by 4 or if the last two digits are 0's. II] DIVISIBILTY TEST FOR 9  A number is divisible by 9 when the sum of its digits is divisible by 9. Therefore, 3+0+5+1+4+3+2+A = 18+A If we take 9 (Option 4), then sum of digits (i.e. 27/9 = 3) is divisible by 9 [as per II] & last two right hand digits (i.e. 92/4 = 23) is divisible by 4 [as per I]. Hence, answer is 4] 9. . Advertisements

If a and b are two prime nos it can take the values 78 as it is the addition of two prime nos 61,17i.e 61+17=78 Similarly 7 can be expressed as the addition of 2 and 5 The last no 23 cannot be expressed as the addition of any two prime nos. So the correct option is 3 i.e 1 and 2 only

The ans to question no 3 is d)none of these as 9+49=58 which ends in 8 and 81+1=82 which ends in 2 so 1 statement in not true Similarly 1+8=9 which is the sumof the cubes of 1 and 2 ends in 9 ans 216+27 which is the sum of cubes of 6 and 3 ends in 9 also the sum of 100+1000 ends in 0 so the third statement is false
