Q) Find the greatest number which divides 85 and 72 leaving remainders 1 and 2 respectively. Ans: Question is asking for highest number which is dividing other numbers…. . clearly, we need to find HCF Since there are remainders after dividing, hence if we subtract remainder from the given number, we will get the actual […]

Q) In the given figure, XZ is parallel to BC. AZ = 3 cm, ZC = 2 cm, BM = 3 cm and MC = 5 cm. Find the length of XY. Ans: Since XZ ǁ BC, Therefore, (BPT Theorem) ∴ ………….. (i) Since XZ ǁ BC, ∴ XY ǁ BM ∠ AXY = ∠
Q) Solve the pair of equations x = 3 and y = – 4 graphically. Ans: Lets plot both the equations on the graph. Increase till these lines intersect each other. Get the intersection point as (3,-4) Since the lines are intersecting at (3, – 4), hence the solution of given equations is (3, –
