four bells commence tolling together and toll at intervals of 2 , 3 , 4 and 5 seconds respectively . in 10 minutes , how many times do they toll together ?
"lcm of 2 , 3 , 4 , and 5 is 60 . so , after each 60 seconds , they would toll together . hence , in 10 minutes , they would toll 10 * 60 seconds / 60 seconds = 10 times but then the question says they commence tolling together . so , they basically also toll at thebeginning ( 0 second ) . so , total tolls together = 10 + 1 = 11 answer : b"
divide(10, divide(multiply(multiply(2, multiply(multiply(add(2, const_3), 2), const_3)), 2), 10))
