(ili) Rohan's mother is 26 years older than him. The product of their ages (in years)Ë // 3 years from now will be 360, we would like to find Rohan's present age. |
|
Answer» Let the age of rohan be x Rohan's mother=x+26 after 3 years, (x+26+3) (x+3)=(x+29)(x+3)=x²+3x+29x+87=360=x²+32x=273x(x+32)-273=0 solve it x=7, Mother's age=7+26=33 |

(i) Rohan's mother is 26 years older than him. The product of their ages (in years)3 years from now will be 360. We would like to find Rohan's present age. |
|
Answer» Let take Rohan's age = x years Rohan’s mother is 26 years older than him Rohan's mother age = x + 26 years 3 years from now Rohan's age = x + 3 Age of Rohan's mother will = x + 26 + 3 = x + 29 The product of their ages (in years) 3 years from now will be 360 so that (x + 3)(x + 29) = 360 or, x²+ 29x + 3x + 87 = 360 or, x²+ 32x + 87 - 360 = 0 or, x²+ 32x - 273 = 0 This is our required equation |

Rohan's mother is 26 years older than him. The product of their ages (in year3 years from now will be 360 We would like to find Rohan's present age |
|
Answer» Let Rohan's age be x ....... Therefore Rohan's mom's age is x+26...... Now Roahn age after 3 yrs x+3 and his mothers age after three years x+29...... Now we know (x+3)(x+29) = 360 ...... ... x²+3x+29x+87 = 360 ...... x²+32x+87=360 ....... x²+32x=360-87 ...... = 273 x(x+32)=273 After solving we get x=7 So, age of Rohan = 7 yrs The solution for how to get x is Take one factor of the equation x²+32x-273 = 0 First factorise .... Factors are x-7 and x+32 ...... So take any one factor and solve it and you will get two solutions of the quadratic equation...... X-7.....x=7 And x+32.....x=-32 Now put your logic age can't be in minus so x=7 is correct solution for this question...Hence solved। |

Volume and Surface AreaQ12:A classroom is 10 m long, 6.4 m wide and 5 mhigh. If each student be given 1.6 m2 of the floorarea, how many students can beaccommodated in the room? How many cubicmetres of air would each student get? |
|
Answer» Given the dimensions of classroom is 10m×6.4m×5m , area = 10*6.4 = 64m² so the volume of the class room will be = 320m³ now each student needs 1.6m² on the floor so no. of Student = room area/(Student area) = 64/1.6 = 40 Students. now volume of air for each student will be = total volume/no. of Student = 320/40 = 8m³ |
