20 people went to a hotel for combine dinner party 12 of them spent rs. 70 each on their dinner and rest spent 4 more than the average expenditure of all the 20. what was the total money spent by them.
multiply(divide(add(multiply(12, 70), multiply(subtract(20, 12), 4)), subtract(20, subtract(20, 12))), 20)
"solution : let average expenditure of 20 people be x . then , 20 x = 12 * 70 + 8 * ( x + 4 ) ; or , 20 x = 12 * 70 + 8 x + 32 ; or , x = 72.667 ; so , total money spent = 72.67 * 20 = rs . 1453.4 . answer : option c"
