for the third time with the cooperation of which organization?Solution
Indian-American astronaut Sunita Williams, along with NASA astronaut Barry Butch Wilmore, is set to fly to space for the third time aboard Boeing's Starliner for its first crewed mission.
Given that (3a + 7b = 54) and (ab = 24), determine the value of (9a2 + 49b2).
The certain sum amounts to Rs11313.5 in 2(1/2) years at 12% p.a., interest compounded 10 months. The sum (in Rs) is:
Find the number of zeroes in 18 × 125 × 20 × 32.
If (2a + b)/(3b - 2b) = 13/2 then 'b' is what percent of 'a'?

   = ?If (a + b) = 17 and (a2 + b2) = 145, then find the value of (a × b).
If x² + y² + z² = xy + yz + zy (x≠0), then the value of (5x+3y-4z)/2x is
when x =4 and y =-6 then find the value of 27x³ +58x²y +31xy² +8y³?
What will come in the place of question mark (?) in the given expression?
?2 = (392 × 224) ÷ (112 × 28) + 62
