after how many years their ratio will become 8:7?
a) 11 b) 7 c) 10 d) 12

Solution: 6x+5x=55, so x=5, put first ratio after substitution is (6*5)/(5*5) and second ratio is
40/35 So difference in numerators 40-30=10 years

Pattern 38:

1) A person ismanufacturing a house. He bought 20 ropes of wire which has a density of 300
Kg/m3. The height of the building to be constructed is 40 m. If the capacity of the current
passed in the wire is 20 A and the voltage capacity is 80 Volts. Then what will be the
opposing force to the current if the wire is used?
a) 2 b) 4 c) 8 d) 1600

Solution: ohms law V=IR, Opposing force of current is resistance, R=v/i

Pattern 39:

1) A horse chases a pony 2 hours after the pony runs.Horse takes 3 hours to reach the pony.If

Solution: Horse takes 3 hours to cover the distance
Pony takes 3+2 =5 hours to cover the same distance, Velocity=distance/time, distance
travelled by them is equal it is 81*3=243km, speed of pony=243/5=48.6
