Ankita's weight is 20% less than that of her grandmother. The grandmother weighs 26 kg less than grandmother's husband, whose weight is 81 kg. If Ankita's brother is 8 kg heavier than Ankita, then what is the weight (in kg) of Ankita's brother ?
Answer & explanation
Correct answer: option 4
Weight of her grandmother = 81 - 26
= 55 kg
So, the weight of Ankita = 55 × 80%
= 44 kg
Now,
Weight of her brother = 44 + 8
= 52 kg
