Question
Six friends F, G, H, I, J and K have different heights.
G is taller than only K. F and H are taller than K but shorter than I, who is not the tallest. Whose height is the third highest in the group?Solution
G is taller than only K. >>>>G>K F and H are taller than K but shorter than I, who is not the tallest. >I>F/H>H/F>G>K Now only J is remaining which can be placed on the blank space. J>I>F/H>H/F>G>K So either F or H is the third highest in the group.
If a = 701, b= 703 and c= 706, then find the value of a³ + b³ +c³ –3abc?
If (a – 8) 2 + (b + 2) 2 + (c – 3) 2 = 0, then find the value √(a +b + c).
...(a – 2) 2 + (b + 6) 2 + (c – 1) 2 = 0, then find the value of a + b – c.
- Suppose [a + (1/16a)] = 3, then the value of [16a³ + (1/256a³)] is:
- If (m + n + o) = 16 and (mn + no + om) = 80, then find the value of (m² + n² + o²).
