\nSolution:
\n\"KSEEB
\nFrom the (i) square
\n1st<\/sup> row 5 + (-1) + (-4) = 0
\n2nd<\/sup> row -5 + -2 + 7 = 0
\n3rd<\/sup> row 0 + 3 + -3 = 0
\n1st<\/sup> column 5 + -5 + 0 = 0
\n2nd<\/sup> column -1 + -2 + 3 = 0
\n3rd<\/sup> column -4 + 7 – 3 = 0
\n1st<\/sup> Diagonal 5 + -2 + -3 = 0
\n2nd<\/sup> Diagonal 0 + -2 + -4 = -6
\n\u2234 It is not a magic square.<\/p>\n

(ii) 1st<\/sup> row 1 + -10 + 0 = -9
\n2nd<\/sup> row – 4 + -3 – 2 = -9
\n3rd<\/sup> row -6 + 4 – 7 = -9
\n1st<\/sup> column 1 + – 4 – 6 = -9
\n2nd<\/sup> column -10 + -3 + 4 = -9
\n3rd<\/sup> column 0 + – 2 – 7 = -9
\n1st<\/sup> Diagonal – 6 – 3 + 0 = -9

KSEEB Class 7 Maths Solutions Question 10.<\/strong>
\nA water tank has stepped inside it. A monkey is sitting on the topmost step (i.e., the first step). The water level is at the ninth step.
\nSolution:
\ni) He jumps 3 steps down and then jumps back 2 steps up. In how many jumps will he reach the water level?
\nSolution:
\nMonkey jumps down = 3 steps
\nMonkey again jumps up = 2 steps
\npresenting this on number line,
\nInitial position = 1st<\/sup> step
\nFinal position = 9th<\/sup> step
\nRepresenting this on number line,
\n\"KSEEB
\n\"KSEEB
\nFirst Jump = 1 + 3 = 4 steps
\nSecond Jumb = 4 – 2 = 2 steps
\nThird Jump = 2 + 3 = 5 steps
\nFourth Jump = 5 – 2 = 3 steps
\nFifth Jump = 3 + 3 = 6 steps
\nSixth Jump = 6 – 2 = 4 steps
\nSeventh Jump = 4 + 3 = 7 steps
\nEight Jump = 7 – 2 = 5 steps
\nnineth Jump = 5 + 3 = 8 steps
\ntenth Jump = 8 – 2 = 6 steps
\nEleventh Jump = 6 + 3 = 9 steps
\n\u2234 Monkey took 11 Jumps to reach 9 steps.<\/p>\n

ii) After drinking water, he wants to go back. For this, he jumps 4 steps up and then jumps back 2 steps down in every move. In how many jumps will he reach back the top step?
\nSolution:
\nInitial position = 9th<\/sup> step. Final position = 1st<\/sup> step
\nMonkey Jumps up = 4 steps
\nMonkey Jumps down = 2 steps
\n\"KSEEB
\nFirst Jump = 9 – 4 = 5th<\/sup> step
\nSecond Jumb = 5 + 2 = 7th<\/sup> step
\nThird Jump = 7 – 4 = 3th<\/sup> step
\nFourth Jump = 3 + 2 = 5th<\/sup> step
\nFifth Jump = 5 – 4 = 1st<\/sup> step
\n\u2234 Monkey took 5 Jumps to reach back<\/p>\n

iii) If the number of steps moved down is represented by negative integers and the number of steps moved up by positive integers, represent his moves in part (i) and (ii) by completing the following; In (a) the sum (-8) represents going down by eight steps. So, what will the sum 8 in (b) represent?
\n(a) -3 + 2 – ……. = -8
\n-3 + 2 – 3 + 2 – 3 + 2 – 3 + 2 – 3 + 2 – 3 + 2 – 3 + 2 – 3 + 2 = -8<\/p>\n

(b) 4 – 2 + …. = 8
\nThus, Sum 8 in (b) represents going up by eight steps.<\/p>\n","protected":false},"excerpt":{"rendered":"
