Step-by-step explanation:
As we know that
As we know thatSP=CP+gain
As we know thatSP=CP+gainGiven 6 times CP is equal to 5 times SP
As we know thatSP=CP+gainGiven 6 times CP is equal to 5 times SP⟹6CP=5SP
As we know thatSP=CP+gainGiven 6 times CP is equal to 5 times SP⟹6CP=5SP⟹6CP=5(CP+gain)
As we know thatSP=CP+gainGiven 6 times CP is equal to 5 times SP⟹6CP=5SP⟹6CP=5(CP+gain)⟹6CP=5CP+5gain
As we know thatSP=CP+gainGiven 6 times CP is equal to 5 times SP⟹6CP=5SP⟹6CP=5(CP+gain)⟹6CP=5CP+5gain⟹CP=5 gain
As we know thatSP=CP+gainGiven 6 times CP is equal to 5 times SP⟹6CP=5SP⟹6CP=5(CP+gain)⟹6CP=5CP+5gain⟹CP=5 gain⟹gain=51×CP=10020×CP
As we know thatSP=CP+gainGiven 6 times CP is equal to 5 times SP⟹6CP=5SP⟹6CP=5(CP+gain)⟹6CP=5CP+5gain⟹CP=5 gain⟹gain=51×CP=10020×CPGain percent is 20%
