sir i have a ques. are u available now??
Yes Razda, go ahead with your doubt.
a+b is a prime no ab is equal to 84 then value of a+b can be assumed as?
Let’s write down 84 as a product of two factors:
Case -1: 42, 2: 42 x 2
Case-2: 21; 2, 2: 21 x 4
Case-3: 7; 3, 2, 2: 7 x 12
a + b=19 is prime only in the last case
quad eqn whose root is reciprocal of roots of 3x^2+4x+2
Let’s write down 84 as a product of two factors:
Case -1: 42, 2: 42 x 2
Case-2: 21; 2, 2: 21 x 4
Case-3: 7; 3, 2, 2: 7 x 12
a + b=19 is prime only in the last case
how many four digit no. divisible by 9 can be formed using exactly two digits
largest no. which leave rem 4;6;2 when divided by 460;690 and 990
